Camikazi Kid - June 6, 1961 - S1-E8
Question: In this episode, Sam leaps into Cam, a teenager with braces. So when Sam looks in his reflection, he sees the braces, even though he's not wearing any himself. Someone submitted a mistake from one episode when Sam's reflection is wearing glasses, even though Sam isn't. While braces aren't as easy to put on or take off as glasses, they're still not part of the body (such as a zit), so shouldn't Sam have braces himself, the same way he'd have glasses on when leaping into somebody? Or should it not be considered a mistake that the reflection is wearing glasses and Sam isn't?
Answer: The obvious answer is that it would be very difficult to fit actor Scott Bakula with braces for an episode. As for the in universe rules, we can assume that items permanently attached to one's body (dental work, pacemakers, artificial joints, etc), would stay with the original body. Otherwise Sam would suffer agony when someone's fillings were jammed into his teeth. You have to have some suspension of disbelief when it comes to things like this. Why weren't Sam's shoes constantly too big or too small? Why does everyone look him in the eye, even when he's posing as someone much taller or shorter?
