Happy Birthday, Dear Hogan - S4-E26
Continuity mistake: LeBeau meets a female underground contact in a movie theater. They have to kiss to avoid detection by the Gestapo. When LeBeau leaves the theater there are no lip stick kisses on his right cheek, but when he returns to camp he has some. (00:18:00 - 00:19:00)
Suggested correction: Simple, they kissed again before LeBeau arrived back at camp. Nothing to see here.
