I assume Carol would have said that "If it was for us, you would've killed him." That's quite a declaration to say out loud about another human being, so it is understandable to squash it. Suffice to say that Carol and Morgan need to figure out how to co-exist.
Came here to post that while Glen and Enid were having another TWD pep talk between characters, a la 'you have to keep living because...' I kept tapping my imaginary watch, wanting to get back to the action. So wasn't the episode for a patented Glen heart-to-heart.
Speaking of male characters who have been spared death for a long time, the problem with Daryl having an awesome moment like he did is that I fear that it may be his last such moment.
