So a detail that's been bugging me after thinking about it at the very end of last night/early this morning...
Finch claims that his cover was blown because he went to a cafe that he used to go to with Grace. So Samaritan has access to video feeds from way back in those days that it...somehow managed to cross-reference from way back then that identified Harold as being Harold? Something about the way this worked doesn't make sense to me. If it can use past records to identify and locate the team even despite their hard-coded cover identities, why would it take visiting that cafe to trigger it? Couldn't it have identified Finch the same way just as easily by catching him walking down a street in NYC that he's likely walked before going dark? Would the overheard word of a waitress thinking that someone looked familiar really be enough to set off a red flag? Would it have been strangely out of character for Professor Whistler to visit a cafe, thus prompting more investigation that way? If all it took was presence at a location they'd been to before establishment of the cover identities, why has Reese never been identified while inside of the police station, a locale he'd been to prior to becoming Detective Riley? Finch being "careless" and getting found out turned into the impetus for this whole current mess, but the way that all went down still feels conveniently suspect to me.
