Leo fully sits back, so Donnie can get situated more comfortably. He's a little worried about if Donnie's going to be able to walk on that leg for the rest of the trip, but he tries not to show it. He doesn't want to stress Donnie out, and he can always piggyback carry him if he has to. They'll make it down to... whatever the Warrens are.

He swivels around to be next to Donnie rather than in front of him, close so their shoulders are pressed together. Then he looks at the candy bar in his hand, like he almost wants to insist... But he does want it...

In the end, he splits the wrapper and takes a bite. A very big bite.
