"Schumacher" is not a name Jim knows; he guesses both that it's some cultural reference he doesn't get due to differences between times (not worlds, necessarily, he knows of the city of Baltimore), and that the person Sol is actually referring to is the little girl in the pedal car (from the way he shouted a heads-up at Jim as she sped his way). "A friend of mine went through the same thing, just before the New Year," Jim offers, sympathetic, "I can't imagine it's what anyone who's already been here before wants to have happen again. I'm glad the two of you had Hellsing to come back to. A support network is always a good thing to have."
