Clint nods, knowing that as far as he can tell, anything's possible. It bothers him a little, because he does like to be able to know what's coming as much as possible, but he clearly doesn't have that luxury here.

And yes, he considers it nothing short of a miracle that she's here and alive. There might be hard times but at least there's good things still happening too.
