Many had been speculating about this for a while, but it was still a WTF moment to see Maggie suddenly reveal to Aaron that shes pregnant. This explains a lot, particularly when it comes to how she has largely been given little of note to do so far in this season, and also sheds some light on just why Glenn was so adamant that his wife stay behind in Alexandria whilst he went out to try and save the day earlier in the season. Whether its the fact that she doesnt want to put her unborn baby at risk by tackling a group of walkers, or maybe the realisation that Glenn couldnt have possibly survived with the sheer number of undead out there, it certainly made for a hard-hitting moment as Maggie refused to step foot out of the sewers and instead opted to return back to the walled safe haven of Alexandria.
