that part where they all kept the door shut seemed more like a dream sequence to me. no way the walkers just stop trying to get in! they just woke up all calm and shit. only sasha and Maggie get up to check the perimeter?
sasha needs to be put in check! if she goes that would suck, but, if she gets someone else killed and then doesn't die right away,
that would be even worse. i feel like the latter is likely what will happen though
as for the clean as fuck douche canoe that surprised Maggie and sasha, well, he needs to die right now! of course they won't just kill him though

it would seem obvious to me at this point that there are others out there that should not be trusted, AT ALL! he is one of them. makes it ever more creepy that he knows ricks name. kinda obvious that he was the one who left the water as well.
