Matthias had already been laughing at his own joke, but it turned into a real fit to see Reed's reaction. He knew she'd have a good sense of humor! Wings would rise, carrying him up and over the cliff side to land loudly by Reed's side. He'd attempt to bump his shoulder against her own as he landed, the laughter finally fading away enough for a retort, "Nah, I've just seen enough butts in my lifetime to say you're the biggest one!" a double entendre; both a jest and a flirt that would likely go over Roxanne's head. A final chuckle would escape him. If Roxanne followed, he'd give her a wing-bump of congratulation for her performance. She was getting better at it every day.
Matthias would then turn to circle and look at the equipment on the ground in interest, "Soo where've you been? Roxanne's been dying to see you, and you're not easy to track down. I even met Balthazar before I found you," at this, he would turn to see her reaction to the male's name. Would hearing the hyena's name elicit a particular response?
