To be fair to Artemy, he regains stoicism rather quickly. He remembers a conversation with Leon, and approaches First Aid, one leather gloved hand out to give him a handshake. It may be more a finger to hand sort of handshake, but it's the meaning behind the gesture that matters, not the size of the participants.

"You must excuse my mannerisms. I have never see anyone quite like you." He remembers a conversation with Qingqiu, and thinks to add, "For reference, where I come from, we have not managed to send man to moon, so if I am rude, please feel free to tell me so I can address my behavior."

With that said, Artemy gives a curt nod, "Another medical professional is always good to have around. Welcome. May I show you around, First Aid?"
