John Greer:  You must be wondering who I am .
John Reese: I think you work for Decima . I think you 're the man to blame for all this .
John Greer: And what gives you that impression , Mr. Reese ? Oh , yes , I know all about you , John . And you , Ms. Shaw . Since your untimely departure from Northern Lights , I understand that you 're in need of a cause .
Sameen Shaw: The only thing I need is an excuse to put this bullet in between your eyes .
John Reese: I got _ one _ . Your company strapped a bomb to my chest and used me to plant a virus , a virus you 're going to tell me how to stop .
John Greer: I do n't think so . I 'm rather invested in the outcome of that virus . Besides , my company adapted its code , but it did n't originate with Decima . We found it on a laptop , the very same laptop that you and Kara Stanton were sent to retrieve from Ordos , China . But if you shoot me , Mr. Reese , then you 'll never learn the name of the man responsible for its creation .
