Scotty: You're an attorney ...
Kevin: Not if I'm on life support. As my husband, you'd be charged with pulling the plug or not.
Scotty: Okay, this is all starting to get a little too real.
Kevin: It's a good thing we are married. If it was up to my mother, she'd never pull the plug and I'd be a vegetable for all eternity.
Kitty: No, come on, Kevin, you love complicated. You-- why did you go to work for Robert?
Scotty: Well, because he didn't make partner.
Kevin: What? No, I wanted to make a difference.
