Sure, he hears Ratchet's voice. And the reassurance is welcome. But at the same time, he doesn't quiet let go just yet. Right. Everything's fine. Sort of...

"Whose is that?"

He jerks his head toward the wall without elaborating. He feels he doesn't need to. And it's then he realizes Ratchet said "we", and not just "me". And slowly levers the medic down to the ground.

"Sorry, I... Got a little concerned there..."

Yeah, he's not letting go quite yet.
