Corrected entry: In the scene where the team first arrive to investigate the bus, the shot where the team is walking towards the bus is used twice. The first time the shot is used Broyles is speaking and the audio syncs with the video. The second time the shot is used Olivia is speaking, but you can see that Olivia's mouth is not moving and Broyles' mouth is.
Corrected entry: Dr. Bishop asks Peter to play him Bach's Mass in A minor on the piano. There is no Mass in A minor. The Mass is in B minor.
Correction: Doctor Bishop has shown himself to have memory problems on several occasions. While a genius in many fields of academic and scientific endeavour, there's no indication that his interest in music is any more than a casual one. He simply remembered incorrectly, which is not grounds for a mistake.
Correction: I think your TV or whatever this was watched on is lagging because I re-watched this episode and could not find this mistake.
