*Spoilers obviously*

Those last 10 minutes
Lori's words to Carl, the baby being born, him having to be the one to put his own mother down.
She knew Rick couldn't and most likely wouldn't do it or maybe he's just been through so much she didn't want to make him do that.

The thing I loved about it is how Herschel could have delivered it and at that point he was up and moving around and could have. He had trained Carol how to do it also. Both of them were missing and separated at the time.

All that preparing was worth nothing cause Maggie had to do it and Lori died because of that. Shows you that in the world they live in now nothing can prepare you for anything.

I'm a big time reader of the comic series and I love the direction they're going in!
