At least he doesn't have to full on drag Jason's body back - that's something, at least. Not to mention that if the other is still moving a little bit, it means he's still capable of doing as much, and that he's also staying awake and alert. Not doing the latter is what kills people in a place like this.

So Bigby just continues moving in the direction of his house. He knows it's not too far off, but.. well, he is moving a little slower than usually when he's trying to support Jason as he goes.

And then that question comes.

While Bigby still moves, it's just met by a gruff: "What do you mean?"
