Plot summary
It's the rehearsal dinner and Christine is excited for "her big day". She has what she thinks is an hilarious speech and gets New Christine all charged up to hear it. Richard is concerned that she'll be upset because he's moving on and she's alone, but Christine insists she's fine. She's invited Todd Watsky to be her date and the more Richard expresses concern the more she inflates their relationship. Todd Watsky turns out to be a jackass, and walks away when he realizes Christine was using him to make Richard jealous. Barb consoles Christine and ultimately Christine realizes she is upset about Richard moving on, but is genuinely happy for him and New Christine. Matthew meets New Christine's sister Amy (guest star Constance Zimmer ) and they end up hooking up at the rehearsal dinner.
