Go to the scene where Young Ed (Ewan McGregor) and Young Jenny come back to the Spectre dance from the lake. When they enter, Norther Winslow (Steve Buscemi) pulls Jenny away and into the dance. But in the following shot, Norther is surrounded by women and he recites one of his poems. Is he a fast runner, or does he have a twin?
Actually, I don't think that's Norther who pulls Jenny aside. He's too far away to get a detailed look at him. Even if it was Norther, there could have been a time lapse which would account for why he was reading his poem in the next shot.
