So what were we supposed to take away from the scene where Daryl visits the grave? Assuming it was supposed to be Carol's grave, there seems to be two possible conclusions:
1) Carol's dead and they buried her (but they never bothered to show the viewer her body)
- or -
2) Carol's missing and presumed dead (in which case why expend the effort to dig a hole only to fill it back in?)
Either way, it seems they've handled the whole Carol situation pretty sloppily. Unless I just completely missed something somewhere.
