Character mistake: There is no way an operative of Q's position and experience would have plugged a device taken from a bad guy into their network. Especially as they had had a security hack only a few days earlier, and this was a security establishment. It would have been thoroughly tested and checked on a stand-alone, air-gapped setup first.

Question: In the opening action scene, while Bond is fighting the terrorist on the top of the train, Moneypenny says "I do not have a clean shot." She has already been communicating with him on radio, why doesn't she just tell him to get out of the bloody way?
Answer: Because Bond is fighting to the death with a man who's trying to throw him off a train. He can't exactly step out of the way.
