Episode #3.5 - S3-E5
Continuity mistake: Danny is on the range firing a chrome/silver Beretta pistol. The other agent on the range takes it from him, but when he is shown shooting it has changed to a black Glock. When he hands it back it has become a Beretta again.
Episode #3.3 - S3-E3
Audio problem: In a conversation with Colin, Zoë says "What is the point of it being able to do all this stuff if we can't see the results?" The camera then cuts away from her face, she continues "We need to find out who [name I won't embarrass myself by misspelling] is talking to." This line has been dubbed in, as it is said while the actress' face is off-screen and in a completely different tone of voice. (00:35:30)
Answer: The shots of the tube station closing and the shot of the concourse were shot at Marylebone station. There is also a shot of the tracks in which a sign is visible pointing to Southwark station and the Jubilee Line, and I suspect this is a stock shot filmed at Waterloo station.
