It isn't until that moment, when she finally takes that step to lean against him, that Daryl realizes he's terrified she won't. It's not about what she's done or what she might do to the group, the others. He just can't lose her like this. He's lost her already, and brought her back, and he's under no illusions about the likelihood of their survival, back home. Someday she's going to run out of luck, or he is, and that will be that. But here-- here if that's the choice she makes, if she walks away, if she leaves--

He wraps an arm around her shoulders, tight, halfway to cover the fact that he's suddenly wound like a spring, almost wired enough to tremble. When he forgives her-- and he will, tacitly, in time, as best as he can-- this will be so much of it, this moment, these choices. He's not letting her go. He's not.
