[Despite himself, Yusuke is a little taken aback by Shaun's response: he'd been expecting some variation on "oh, really?", not an invitation to travel with him. He manages to refrain from lapsing into an awkward pause, however, valiantly pushing past his own feelings of surprise to say:]

Oh, uh... actually, I was wanting to know if you'd be interested in just taking her off my hands - y'know, since she likes you so much better than me.

Probably because he doesn't often call kids up offering to give them a monster bug. You are expanding his horizons in the weirdest of ways, Johto. :I]
