With four pages left, Jason makes his second appearance and his first speaking one.
I kind of feel bad for him. I had plans when I introduced him. He'd be filling the Charlotte role for Abby, but not know Mark's double identity and, as such, hilarity would ensue. He's had his moments, but other plots have taken on a life of their own, so he's had a lot less screen time. Still, I know his appearance here in #12 will make a bit of an impression.
Bonus points to anyone who can figure out what movie they're talking about. There is one.
