I never noticed that Daryl looks down at their hands. Not only is he holding her hand back, but he’s observing it. Because all through his life, no one has hugged him, held his hand, listened to his problems. Beth has done all of that for him in a few short days, and I think this is about the time he realizes that Beth is someone he needs in his life. Beth doesn’t truly know Daryl, through the series they’ve never really been close. But they’ve been given this chance to know each other.
