End Game (1) - S8-E7
Revealing mistake: Boyd has a video-conversation with Linda on the phone she sent him. On top of the screen you can see how long the video will last (1 minute and 3 seconds), showing it's a pre-recorded video, not an actual live conversation.

Somewhere in the World It's Christmas - S4-E15

Revealing mistake: When Alex is talking to Rebecca Pope at the end of the episode, we hear Alex say "Now I know more about you than my friends."
