From TVGuide:

What came with the decision not to show Carl actually shoot Lori? Part of me hoped that could mean she's still alive.
Kirkman: You don't want to show too much of that stuff. I think we showed quite a bit in this episode. A lesser show would have a zombie Lori lurking in the prison and doing all kinds of nefarious things. That would be an absolutely hokey, ridiculous thing to do. That's certainly not something we're trying to set up. We were just trying to step back and do this in a little bit more tasteful way.

So that's that.
