I don't think Morgan would be hiding behind Darryl and I don't think the two know each other for Morgan to just trust Darryl at this point. Morgan has been on his own from the start and has survived.

Darryl was with Carol who ended up at the hospital. It makes sense it is Noah with him. I wouldn't be surprised to not even see Morgan this season as he could keep following the group and take awhile to catch them.
