That is my point. Rick left him on his own, so it seems his continued isolation will only worsen his mental state.
I realize that the plot called for Morgan to only be in one episode (most likely the actors scheduling conflicts) but I also think that Rick did not try harder to bring Morgan back to the prison because he already has too much on his plate with Merle, the Guv, etc. and Morgan's instability could be another factor that could cause a fatal mistake.
oh yeah absolutely. I'm just hoping he gets worked back in some way or another because Morgan is a really good character.
