Something I didn't understand (SPOILERS)
Ok, so I get that Kenny dressed up as the magician's assistant. But this leaves a few things unexplained.
1. What happened to the REAL assistant? She was definitely there in the beginning of the movie, when the train is being boarded, and we see her again later after the train has been evacuated, talking to Ken. I'm POSITIVE that isn't Kenny...the hair is different, and so is the voice. It's definitely a woman...but I don't see this character listed in this movie's credits.
2. How did the magician not know that was an impostor? There are a few times when Kenny (dressed up as the assistant) and the magician interact, during their magic acts, and there are no signs that Ken notices anything is wrong.
