If in the reunion, Daryl doesn't hug Carol, just acts the same way he did, when he met the group in the wagon? Don't you think it would be a final answer that Daryl loves Carol in the same level he loves the others?
Well, I don't think it's as straight forward as that. SO MUCH will depend on the circumstances of the reunion - where it happens, what's happening around them, if Daryl has seen her from afar etc.
It is also entirely possible, even if the circumstances were perfect that the lack of a hug could still come over as believable and meaningful. It could be played as awkward and tension filled, because of what has gone on while they were apart, neither sure where the other is emotionally.
I know some fans think Beth has changed his life forever and ever, and he's now an open hugging book, but he seemed to go back pretty quickly to his old ways once Beth was gone. A lot of people expected a Rickly hug, and we didn't get that, but there was no doubt that relationship was solidified on screen.
I can't say that no reunion hug means Daryl just feels the same about Carol as everyone else, but I can say i would be disappointed simply because I want to see one. For me, a lot more will have to play out in season 5 (namely the bottle episode) before I make any judgements about what they are saying about how Daryl feels for Carol.
