If the circumstances were normal he'd find it cute, the way Drift doesn't realize he's the important one. But Wing's spent a little too long alone and in dire straights, so he's maybe a little desperate for the contact, the final reassurance that he's not hallucinating.

And he does draw strength from that grip, inspired by love, the smile gaining fortitude that passes back to the body, squeezing around Drift's hand.

The smile turns a little rueful though, because he sees the worry in Drift's optics, and he knows in the process of his foolhardy quest he put not only himself in danger but his rescuers too. "I... I'm sorry."
