SCP-021 Bloody Knife

**SCP-021 MUST BE CONTAINED IN SIGMA-2 AND CANNOT BE EXAMINED BY MORE THEN A GROUP OF 7 AT ONE TIME.**

SCP-21 is a bloody kitchen knife, similar to Michal Myers' knife from the Halloween series. It is always covered in blood, which is always unidentifiable. The way SCP-21 works is very dangerous, and is to be taken with extreme caution if ever interacted with.

SCP-21 is as stated before, a knife. While it appears to be a normal knife. If there is EVER more then a group of 7 within 30 Ft of SCP-21, then the anomalous ball will start to get rolling. At first, the 7 will start to interact for no reason, starting to make conversation with each other and making jokes, and if the subjects were at an event then they will comment on it and refer to it as a major point of their lives. Then, out of nowhere whatever light source is illuminating the room will flicker or go out momentarily until one of the subjects relights it, only to discover one of the seven (or more depending on the group) has SCP-21 imbedded in their back, almost like they were stabbed. The remaining subjects will then panic, and one will randomly shout out "there has been a murder!" which will get the rest into stereotypes that can be found in most murder mystery movies depending on the group size. if the group is seven people, then the following stereotypes will be presented:

One will be the deceased victim, who generally acts like a rich party goer and trusts to many people.

One will be the corrupt best friend who the dead subject will think could never betray them.

One will be the "good guy" detective, who is abnormally good at figuring things out and it should be noted that this person will always [Redacted]

Another will be the coward, who can also never be the killer but will be suspected by the good guy detective and accused a few times by everyone else.

One will the the harsh ex lover, who either still has a love for the subject (which means they are not the murder) or they will have a massive resentment towards the victim which raises the chances of them being the murderer.

One will be the current lover, which honestly is less of a clear chance of them being the murderer as they are the only stereotype that retains some of the original person in their stereotype.

And the final stereotype in a group of seven is a clearly corrupt figure, such as a lawyer or a judge or sometimes a royal figure, which honestly sucks because it makes my algorithm (hi this is 05-3 by the way the scientist researching this ended up being the victim and I am just using his notes) super just f\*\*\*\*\* up, and makes my job of containing SCP-21 way harder.

To re-contain SCP-21, the subjects must discover the killer (with subliminal messages from my algorithm) that are able to help the subjects find the victims as quickly as possible. It uses the subjects actions and words to examine what stereotype they fit, and starts to eliminate potential killer's. The more people there are the more stereotypes that are added to the mix making it harder for the algorithm to function, and sometimes requires more deaths to find the killer. After the event with SCP-21 the subjects will have their memories erased and even with memory recovering pharmaceuticals they will still not have any memory of the event.
