Caught up as he is in his nostalgia-driven giddiness, Gordin's unaware of the quake he's put in Annie's confidence. ...Not that he can really claim to do the same, not without much arm-twisting; archers are built for support and mopping up messes, not for going in guns blazing. Being a hero is all about perspective, of course.
Not that he's thinking about that either, not when he's trying to imagine what snow goons look like.

"You defeated snowgoons?" Gordin, no that makes it sound like they're pokemon-- Oh, whatever. "Snow's terrifying at the best of times; you must have had a lot of trouble to fight in it! I think that's plenty heroic-- Oh, but I'm getting ahead of myself. What's really important is that you did it to help people, of course...Were these snowgoons here in this city, or back at your home? I don't fancy facing down some myself, so I might have to ask your help if they're here!"

Gently clapping a hand on her shoulder, he leans in a little and nods firmly. "If that's alright with you, of course. I know that you must have other things to do, too. But one day, I'd like to fight alongside you and see how a hero works."
