PROBLEM: Dr. Clark Murray:  Note the rectangular bruising around these wounds here and here .
Kate Beckett: Mm - hmm .
Dr. Clark Murray: Caused by the hilt of of the knife striking with force enough to compress the skin .
Kate Beckett: And as a result , the injuries penetrate deeper than the actual length of the blade .
Dr. Clark Murray: He 's also honed the blade so fine , it 's brittle enough for bits to break when it strikes bone , which is why slivers of blade were found inside both of his victims . We now know those slivers come from the same murder weapon .
Kate Beckett: Wait , two victims ? How many people has he killed ?
Lanie Parish: _ Five _ , that we know of .
Kate Beckett: So we 're looking at a serial .
Dr. Clark Murray: Well , yes and no . We believe we 're dealing with a professional . Someone with extensive military training .
Kate Beckett: A contract killer .
Dr. Clark Murray: I used tomographic reconstruction of Coonan 's wounds to generate a 3D model of the blade used . It 's a Special Operations Group knife , the kind favored by Special Forces in Gulf War I. He kills with a single blow , using these other wounds to camouflage the skill with which the initial stroke was delivered . The very same method and the very same weapon that the killer employed ten years ago .
Kate Beckett: Lanie ...
Lanie Parish: I 'm so sorry .
Dr. Clark Murray: Detective Beckett , there is no doubt in my mind that Jack Coonan was killed by the same man who murdered your mother .

SOLUTION: victims

PROBLEM: Illyria:  I traveled all of them as I pleased . I walked worlds of smoke and half - truths , intangible . Worlds of torment and of unnamable beauty . Opaline towers as high as small moons . Glaciers that rippled with insensate lust . And one world with nothing but shrimp . I tired of that _ one _ quickly .

SOLUTION: worlds

PROBLEM: Cole Parker:  Do you really think the C.I.A. would put its entire database of secrets in his head ? He 's a pathetic weakling . How could they send him on assignments ? How could even withstand torture ?
Sarah Walker: It 's true . He 's just a Computer and Electronics Technician , a brave _ one _ , but he 's not the Intersect !
Alexis: Then who is ?
Cole Parker: Me ! I 'm the Intersect !
Chuck Bartowski: NO he 's not ! It 's me ! Okay and I resent the fact that I could n't stand up to torture . Do your worst . In fact , you could stick that incredibly long needle in my eye and I still would n't tell you anything !

SOLUTION:
Computer
