The Red Lion doesn't seem at all bothered by her hand being there, in fact, she doesn't seem to really understand the gesture at all. Lance nods when Anna talks about how advanced she is.

"She's even got her own life force, and I guess she's what reminds me I'm real and alive y'know? Because I wouldn't be able to connect with her if I didn't have one too," then he grins, "She's also the fastest lion in Voltron, she can reach the edge of the solar system in a few minutes, but uh… we'd have to be inside her cockpit to survive that. But it also means we can totally stop by your place real quick if you wanna pick up our jacket and helmet."

With that, he jumps up onto the lion's back and holds out a hand to help her up behind him if she needs it.
