[He's more interested in hearing about the mobile suits since Trowa hasn't exactly gone into detail about everything. He gets that they're weapons of destruction and that they aren't sentient like Baymax is, that they're meant for specific purposes, but they also have zodiac names and that's weird to him. He doesn't get much of a chance to dwell on it (but the look on his face should be enough for Heero to notice he's thinking of it) before the other boy asks him that.]

I designed our armor by myself and I've made other robots with blueprints. I think I know what I'm doing. Why? Got something in mind?
