It's surprising and a little sad that Daryl is now the only likable character in the whole group. Of course, this means they'll either make him pull a Shane, or kill him off before season's end. And he'll probably end up dying for something stupid, like saving Sophia. Ugh.
Seriously, does anyone even care about that girl anymore? I mean, I had pretty much zero sympathy for her to begin with (if you're too stupid to follow simple instructions meant to keep you safe and alive, then screw you, you deserve to be eaten by zombies), but it's been so long since the girl was a part of the goings on that, even if I had cared, by this point I'd say I've written her off as lost and grieved for her death. And, really, is there any outcome to the scenario that would be satisfying at this point? Either she's alive (thanks, kid, a good man - Otis - had to die because you're a friggin' moron), or she's dead (boohoo, I'm so over it), or, if we're lucky, she's been zombified and we get to see someone put a bullet in her head. But, in my opinion, none of those outcomes really justify all the time wasted - by which, I mean, the show time dedicated to the search, time that could've been used to advance the story, which is pretty damn precious since there are only 13 episodes to the season and we've spent how many now with people wandering in the woods?! - on looking for her. Shy of Merle showing up, blitzed out of his mind on PCP, with the little girl's hand grafted onto his stump and wearing her face as a dead skin mask, back to slaughter everyone who left him on that roof, I'm not able to think of a resolution that'll leave me thinking, "That was so worth the wait, because the buildup really paid off in the end."
Speaking of Merle, I'm glad they brought him up in this last episode. Because, yeah, what the hell? They made only a half-assed effort to search for him. And Rick was even more responsible for Merle's situation than he was for Sophia's. But, what, because he was a racist, druggie scumbag he wasn't worth looking for, possibly getting people killed for? Some ripe hypocrisy on Rick's part there.
As for the zombies in the barn...yeah, I'd say it's a given that Herschel rounded up infected family, friends, farm hands and neighbors, or any walkers that strayed onto his property, and locked them up, not wanting to kill them for religious reasons or because he's just f'ed in the head. Question is: now that Glenn stumbled upon the secret, will the chick push him into the zombie pit to keep him from telling Rick? I kinda hope so.
