Oh! He didn't know this guy could make that face! Not that he had a lot to go on, but, y'know-- it's kind of nice. Even if Caspar couldn't begin to guess why Byleth would look so excited to see him; maybe he mistook him for someone else? He does look a little disappointed when he realizes it's just him - Caspar feels a little bad, honestly.

He's also a bit surprised Byleth knows his name - but, hey, always possible he heard it from his father when his group was working with the Empire.

"Ah, well-- thanks, anyway. Worth asking around, right?" There's a hesitation in his voice as he responds; that immediate answer aside-- something to discuss.

He can't imagine that a mercenary who simply did what was in his best interest would feel the need to talk things over with the son of an employing army's commander, but that's all that comes to mind. Is there more to it? Dimitri doesn't remember the war - almost like it never happened to him. Does Byleth, in turn, remember something Caspar doesn't?

But what could he possibly know that involved Caspar?

Maybe that's just it. Maybe he's as surprised to see a dead man as Caspar is to be here.

Well-- there's only one way to find out. Caspar shakes off that momentary hesitation - clearly, they do need to talk, and who would he be if he turned down the chance to spar with such a famed mercenary? "Uh... yeah. Yeah, sounds like a plan to me! Where do you want to spar?"
