They showed Carl com across him at gas station but Rick came along and scared him off. Carl was wanting to help him and Rick was cautious and wanted him to stay away. They showed in episode, maybe first or second, where there was a lot of time jumping and folks couldn't figure out where this bit fit in. So now time is caught up and Carl is, against Rick's wishes, still trying to help this guy.
So is Maggie going to lose or will have already lost her pregnancy and this baby Gracie that was brought back will be her fill in baby?????
