SCP-1620: Reflection Infection 


Item #: SCP-1620 
Object Class: Euclid 


Special Containment Procedures: SCP-1620 is to be contained in 
a sealed room with walls and ceiling painted a flat, non-reflective 
grey color, with the object's inner surface pointed away from the 
door at all times. No reflective surfaces of any kind should be 
brought into SCP-1620's containment cell, including camera lenses. 
Personnel wishing to enter SCP-1620's containment to attempt a 
sample must obtain Level 4 authorization, dress only in non- 
reflective clothing, and submit to a 24-hour isolation period 
afterwards to ensure no accidental spreading of SCP-1620-1. 


If an individual is determined to be infected by SCP-1620-1, they 
must be placed in an opaque container with an air supply and 
immediately transported to an isolation cell with a single movable 
mirror and no other reflective surfaces. The mirror must be placed 
flat against the floor or wall whenever another individual is present in 
the cell, and otherwise used only to track the development of 
SCP-1620-1. Once SCP-1620-1 has reached stage 3 maturity, the 
mirror must be removed and the subject contained for a further 
minimum of three (3) months. Upon completion of the isolation 
period, if the subject views their reflection without any sign of 
SCP-1620-1, they may be released back to normal duty without 
incident. 


Description: SCP-1620 is a sheet of rectangular metal alloy, 
measuring approximately 2m x 2.5m x 0.25m, curving at an angle of 
2.5 degrees along the long edge. One of the short edges is torn and 
jagged, while the remaining three edges are smooth at perfect right 
angles. Spectroscopic analysis of samples taken from SCP-1620 
proved to be inconclusive, though high concentrations of both 
titanium and tungsten were registered. The ‘outer’ side of the 
object's surface is blackened, scarred, and pitted in a manner 


resembling exterior surfaces of man-made objects that have 
survived atmospheric re-entry, and exhibits no anomalous 
properties. SCP-1620's inner surface has an extremely high 
reflectivity, and causes all known manifestations of SCP-1620-1. 


When a human being or other humanoid living organism is reflected 
in SCP-1620's inner surface, they become host to an instance of the 
organism identified as SCP-1620-1. SCP-1620-1 is a noncorporeal, 
parasitic entity that copies and replaces humanoid reflections. As 
such, it is only visible or interactive when it can be viewed ina 
reflective surface. The entity's development progresses through 
three distinct phases over a period ranging from one to ten weeks, 
designated Stage 1 through Stage 3. 


Infection Stage 1 lasts between six and eighteen hours, starting from 
the time the host is exposed to SCP-1620 or a reflective surface 
currently displaying an instance of SCP-1620-1 in Stage 3 maturity. 
During Stage 1, the entity is visually identical to its host's actual 
reflection, and cannot be distinguished as abnormal by any 
individual other than its current host. Over the duration of Stage 1, 
the entity will become increasingly desynchronized from its host's 
actual movements, starting with a slight ‘lag' effect as it belatedly 
attempts to imitate the host, and gradually progressing to the point 
where it behaves completely independently of the host. 


Infection Stage 2 lasts between twenty-four hours and seven days, 
though the transition point between late Stage 1 and early Stage 2 is 
difficult to identify. During Stage 2, SCP-1620-1 remains capable of 
visually independent activity, though it remains incapable of actually 
affecting the environment outside the reflective surface it is currently 
displayed in. When in view of humanoid organisms other than its 
host, SCP-1620-1 will attempt to imitate an ordinary reflection, 
though the ‘lag’ effect developed during Stage 1 remains. If 
apparently alone within its host's field of view, the entity exhibits a 
friendly and non-hostile demeanor, using body language to present 
a non-threatening attitude. When observed remotely and not in view 
of its host, however, SCP-1620-1 can be seen studying its host with 
anger or outright hostility, often accompanied by subtle or overtly 
threatening gestures. As Stage 2 progresses, the entity begins to 
diverge in visual appearance from its host as well, gaining or losing 


body mass, altering facial features, and changing overall body type. 
When SCP-1620-1's visual appearance has stabilized, it is 
considered to be in Stage 3. 


Infection Stage 3 lasts for an indeterminate time, currently not 
known to exceed nine weeks. During Stage 3, SCP-1620-1 reflects 
as a vaguely recognizable and heavily distorted image of its host, 
varying by individual but adhering to certain commonalities. Based 
on conducted testing, the appearance of a Stage 3 entity is believed 
to be a facsimile of the host's own subconscious self-image, rather 
than their outward physical shape. Notably, whether by accident or 
malice, SCP-1620 appears to latch onto the host's most negative 
self-portrayal, typically causing them great distress in the process. A 
Stage 3 instance of SCP-1620-1 is considered contagious, capable 
of spreading itself to the reflections of any suitable host currently 
displayed in whatever surface it is occupying. 


For the duration of Stage 3, the entity ceases to placate or interact 
invitingly towards its host, instead exhibiting actively threatening or 
mocking behavior regardless of if the host's attention is currently 
directed at it. Whether threatening the host or ignoring it entirely, its 
actions exhibit intent to either distress the host and induce it to seek 
help, or to draw the attention of onlookers and allow its propagation 
more directly. When Stage 3 reaches its conclusion, the entity 
appears to ‘die’, reversing all changes made to its appearance in 
minutes and returning the host's reflection to normal. To date, no 
individual known to host a Stage 3 instance of SCP-1620-1 has 
reported a recurrence, though host individuals have a high (60+%) 
chance of developing mild to severe catoptrophobia. 


Experiment Log 1620 


Date: 04/12/ : 

Procedure: D-class personnel given, individually, a 
lighter, blowtorch, gas-welding torch, and flamethrower. 
Each subject instructed to approach SCP-1620 and 
attempt to apply a scorch or burn mark to either surface. 
Details: All attempts to mark or damage SCP-1620 by 
means of heat met with failure. D-1620-4 refused to 
cease use of the flamethrower on command and was 
terminated. The resultant explosion also had no effect on 


SCP-1620. 


Date: 04/14/ : 

Procedure: SCP-1620 removed from containment and 
transported in a sealed, opaque container to an outdoor 
location for destructibility testing. D-class personnel 
given various construction tools including saws, drills, 
claw and sledge hammers, and handheld jackhammers, 
and instructed to attempt to cause visible damage to 
SCP-1620's surface. 

Details: All manner of handheld tools failed to scratch, 
dent, or mark either surface of SCP-1620. Application of 
a pneumatic jackhammer to the object's damaged side 
succeeded in dislodging multiple samples. Samples 
removed for further testing. 


Date: 04/18/ : 

Procedure: Subject D-1620-5 deliberately exposed to 
the object and allowed to develop to Infection Stage 2, 
then instructed to interact with SCP-1620-1 and ask it 
questions. 

Details: SCP-1620-1 made no attempt to return 
interaction, instead smiling at D-1620-5, nodding 
pleasantly, giving small waves of welcome, and 
occasionally miming hugs in the air. When D-1620-5 was 
seen to be looking away from the mirror, SCP-1620-1's 
expression became flat and contemptuous, baring its 
teeth and reflexively clutching empty air in a strangling 
motion or drawing a finger across its throat. 


Date: 05/04/ : 

Procedure: Live orangutan exposed to SCP-1620, 
placed in isolation and observed visually via remote 
camera within view of a mirror. 

Details: Fourteen hours after initial exposure, 
orangutan's reflection viewed to be acting independently 
of its host as normal for a Stage 2 entity. Orangutan 
seen to exhibit great distress, behaving in a threatening 
manner towards its own reflection as it would another 
hostile orangutan. 


Date: 05/11/ : 

Procedure: Live iguana, live bull mastiff, live tuna, live 
African grey parrot exposed individually and sequentially 
to SCP-1620, placed in isolation and observed visually 
via remote camera within view of a mirror. 

Details: All test animals and their reflections failed to 
exhibit anomalous behavior as far as 72 hours after 
exposure, at which point testing was aborted. 


Date: 05/16/ : 

Procedure: Subject D-1620-6 exposed to SCP-1620, 
allowed to progress partway through Infection Stage 1, 
then instructed to approach a mirror and destroy it while 
SCP-1620-1 was exhibiting anomalous movement. 
Details: Mirror shattered without resistance. SCP-1620-1 
visibly unharmed when next seen in another reflective 
surface and showed no reaction to its host, though 
hostile and abusive gestures towards the host in Stage 2 
increased greatly in frequency and forcefulness. 


Date: 05/18/ : 

Procedure: Subject D-1620-7 exposed to SCP-1620, 
allowed to progress into Infection Stage 2, then placed in 
a room with two mirrors on opposite sides. 

Details: SCP-1620-1 exhibited standard anomalous 
behavior for a Stage 2 maturity state, but all visible 
copies of SCP-1620-1 moved and acted in total unison 
and synchronization. 


Date: 05/23/ : 

Procedure: Subjects D-1620-8 and D-1620-9 exposed 
to SCP-1620, allowed to progress into Infection Stage 3, 
then restrained together in a room with a single wall-to- 
wall mirror. 

Details: The subjects’ parasite entities, designated 
SCP-1620-1a and SCP-1620-1b respectively, responded 
to each other's presence with excessive hostility. Both 
entities abandoned any pretense at staying with their 
hosts, travelling 'across' the room in the mirror and 
physically attacking each other. Upon the apparent 


victory of SCP-1620-1a involving its opponent's 
[REDACTED], D-1620-9 went into immediate 
convulsions and died of an apparent brain hemorrhage. 
D-1620-8 suffered no visible physical injuries, but went 
into hysterics and repeated insistence that 'that wasn't 
him, he wasn't really like that’, requiring sedation before 
removal.

SCP-1621: A Useful Plant 


Item #: SCP-1621 
Object Class: Keter 


Special Containment Procedures: Exactly one colony of 
SCP-1621 is to be kept intact within Bio-Containment Area-09. 
SCP-1621 byproduct is to be collected for use by the Foundation as 
a component in rocket fuels, in industrial cleaning and etching 
operations for semiconductors, in nuclear reactor fuel processing, 
and other industrial operations. and disposed of within a stainless 
steel burn chamber. The containment chamber, collection 
equipment and airlocks must be constructed entirely from stainless 
steel or copper. Under no circumstances is water to be released 
above soil level- subsurface irrigation is sufficient for SCP-1621's 
hydration. 


Mandatory Level A Hazardous Materials suits, as well as CO2- and 
light-delivery equipment is to be polymer! -sealed to prevent CloFg¢ 
vapor reactions. 


In the event of a containment breach, all personnel are to 
immediately report to their assigned safe room. Upon detection of 
CloFg vapors beyond .01 ppm within the safe room, or once all 
reported personnel are within the safe room, the safe room will seal. 
When all safe rooms have been hermetically sealed, BCA-09 will 
flood the facility and containment chamber with liquid nitrogen. 


All colonies of SCP-1621 not earmarked for transfer to BCA-09 are 
to be isolated and destroyed. SCP-1621 has proven resistant to 
indirect force, radioactivity and heat, theoretically as a defense 
against its own reactions. Redirection of local water supplies to 
induce permanent flooding is preferred; if impractical, the infestation- 
and a 10m radius beyond- must be tilled under to a depth of 2m and 
treated with liquid nitrogen to neutralize the vines, stalks and roots. 


Description: SCP-1621 is an invasive, flowering mimic vine similar 
to Rhizophora, Tetracoccus, Rafflesia, Viola and Passiflora. While 
no specimen of SCP-1621 has ever exhibited sentience or sapience 
of any sort, all specimens mimicked, albeit imperfectly, locally 
indigenous species, which originally lead to sub-classifications of 
SCP-1621. Note, however, that only one genotype of SCP-1621 has 
been identified- all variants are merely adaptive camouflage. 


Analysis of the chemical hazards of SCP-1621 follows: 


The flowers, roots and vines of SCP-1621 utilize chlorine 
trifluoride in place of sap or nectar. ClaFg vaporizes at 13 
degrees Celsius, is colorless and smells sweet. 
SCP-1621 must fertilize itself to expand the colony. The 
sweet scent of CloF¢ attracts insects and animals, which 
at 800 ppm is lethal within fifteen minutes? and 
incapacitating far sooner. 


SCP-1621 sap and nectar are corrosive, toxic, hypergolic 
on contact with most combustible materials without a 
spark or ignition source, react violently when in contact 
with water, ice, or silicon-containing compounds 
(including sand, asbestos and glass), is incompatible 
with oil, grease, reducing agents, organic compounds, 
fuels and combustibles and most metals and metal 
oxides, cannot catch fire and so cannot be neutralized by 
ignition and decomposes into chlorine, fluorine and 
hydrogen fluoride gasses if exposed to temperatures 
higher than 220 degrees celsius. 


Disposal can be safely managed by exposing equal parts 
sap/nectar with kerosene and collecting the resultant 
vapors for distillation into component elements. 


The root structures of SCP-1621 are approximately doubled in area 
as those it mimics. If provided with nutrients from carrion, it will also 
extrude vines in all directions at a visibly observable pace that 
continues until the carrion is dissolved and the nutrient supply 
exhausted. Provided with enough carrion, SCP-1621 expands ata 
rate of m/h. Stationary objects are enveloped, slowing during 


vertical movement, but typically one or more instances of a CloF¢ 
reaction have reducted stationary objects to rubble, scrap or ash. 
Once a vine can do so without overlapping with the host stalk, it 
penetrates the soil and begins to sprout, creating a new stalk 
expanding the colony. In all but the most arid climates, SCP-1621 
wipes out all other plant life around the colony by way of corrosion, 
and through CloF¢ reactions triggered by rainfall. 


Addendum: Fruit-bearing specimens do not contain CloF¢ and, in 
fact, if they can be harvested safely, have proven safe to eat anda 
close approximation of the fruit mimicked.
