Patch smiles. Good. She's glad to help, and also to be helped. She'll feel much better, with everything she needs close at hand, no matter the situation. She puts on her safety restraint while Peter does the same. Then, after a moment - "Between your legs." When that doesn't immediately explain itself, Patch reaches down between her own, and pulls up an additional strap, meant to click into the bottom of the buckle in the center of their chests. Presumably for if the vehicle rolls, and Patch isn't sure what they're going to find out there. Seems prudent.

Once they're ready to go, she pokes around until she finds the control for the first set of sliding doors that will let them out onto the surface. Patch assumes that ones they pass through these, they won't open behind them without sending everything through a decontamination procedure, and they will have to continue through the next (currently closed) set, so she asks: "You sure you've got everything?"
