The Walking Dead2010

[Maggie and Aaron talk about Glenn while crossing under the community wall through an underground sewer tunnel]

Maggie Greene:
If he's alive...

Aaron:
If?

Maggie Greene:
He told Michonne he would've found some way to signal us if he got out. If he's alive or he's hurt or trapped maybe taken. If he's alive, he needs my help. That's why I'm doing this. And if he's dead, I don't want to be waiting on him. None of this is your fault you don't need to do this.

Aaron:
People are dead. I was a part of that. And I have to live with that.
