I am the world. You must all die! Person of Interest : The machine is very good at spotting threats to itself and in a flashback we see that it considered Finch's partner to be a threat. At the end of "Legacy," it viewed Reese as a threat, too, and tagged him with a red box. As of "Firewall," it seems to be prepared to work with Reese to rescue Finch from Root. The machine seems quite attached to Finch overall, especially in flashbacks. When he first began testing it, he had to teach it that he was not special and did not deserve extra protection, and it's revealed that the machine also set him up to meet his future wife, simply because it was able to look at her life and see that she was a match for him. The Vahki robots were the first clear examples. Built to act as law enforcement in the city of Metru Nui under the command of Turaga Dume, they just as easily took orders from an impostor when Dume was kidnapped and replaced. They eventually got fried by a citywide power surge, but the ones who survived had their programming warped to Kill All Humans -- after all, the law can be enforced easily if there's nobody alive to break it (thankfully, they didn't fare well against the invading Visorak ). Then came the revelation: Vahki were A.I.s built by A.I.s -- as it turned out, the first 8 years of BIONICLE
