IMO Morgan is one of the best characters in that universe and there is no doubt that Lennie James is one of the best actors. Morgan can't go out at the hands of a cartoon villain like Ginny unless James hasn't decided if he wants to come back so it had to be a cliffhanger.
From a storyline perspective, if he survives it has to be:
the helicopter/ Rick people which I find the most likely
or Sherry
