Oh! Maes is gonna remember his birthday! That's a good start. Sora almost forgets to keep an eye on the road, he's so excited about the possibility of someone else on the birthday train.

This is an interesting way to stumble into this particular end of his... situation. "Well, uh... I guess the easiest way to explain it is that I'm a bodysnatcher?" He laughs! "No, I'm kidding. There is more than one person in here, though. August 14th's the other guy's birthday."
