Georgie: [sighs] I thought you might like a little baby time. Mary Cooper: I would. Georgie: But first... I need you to fix this mess with Audrey. Mary Cooper: I'm not the one who needs to fix it.

Georgie: I really want to thank you for trying to straighten things out with my mom. Audrey: I'm glad someone appreciates it. Georgie: For what it's worth, I think Mandy was a little out of line. Audrey: I'm used to it. Everything's always my fault. Georgie: Not true. Getting pregnant... that one, she blames square on me. Audrey: As do I. Georgie: She had a little something to do with it, but I'll spare you the details. Audrey: Thank you.
Georgie: As for my mom, I can't tell you how many times she's butt heads with my dad, my meemaw, my sister, Sheldon, of course. Heck, once she had a falling-out with Jesus. Audrey: Poor Jesus. Georgie: Yeah, hasn't he suffered enough? Audrey: She ever fight with you? Georgie: I dropped out of school and got a girl pregnant at 17. What do you think?
