[Another moment of staring goes here, and Junpei finally comes to the conclusion that Minato is being completely serious about this.]

Uh... okay, wow. That's pretty... [Nuts? Bizarre? Insane?] interesting. [All things considered, it's not really a BAD thing; Junpei had spent most of his life wishing he had real friends, and now he had several that he wouldn't have traded for anything on earth. Learning that he had more in some parallel world wasn't bad news, it was just WEIRD. He lifts a hand to adjust his cap, then gives Minato a mildly perplexed look.] So ah... what's she like? I mean, I guess if all you guys were surprised by her then she'll be expecting me to not necessarily know who she is, but that kinda sucks for her. I'd feel bad running into her and just not knowing her at all.
