A lot of fans think this may be it for Maggie, between how upset Lauren Cohan was when she was on Talking Dead when Hershel was killed, and that scene of her burning the photo.
As for the episode - I'd actually expected worse from what I'd heard online. I enjoyed the big reunion between Maggie and Glenn and the quiet moment when they were alone. I like that they are their own little world. I appreciate Glenn's friendship with Tara and how he repaid her for her trying so hard to help him. The Daryl stuff wasn't all that interesting (I guess this his low point as he doesn't feel he will ever have more), but I do think Joe is fascinating; very much like a colder, less volatile, more dangerous version of Merle Dixon.
I was happy to see Rick, Michonne, and Carl again. For about sixty seconds. I love that little group.
The only real downside was Abraham, Eugene, and Rosita. Eugene is amusing in small doses but the other two seem brain dead for believing him. And whoever plays Rosita can't act.
