I think I have to disagree with you both here. I completely buy that reaction from someone on the eve of their wedding day, who has been through so much to come to terms with the fact that this is the right decision. The scene with him hugging his Dad, was one of release of his personal demons and of what lay ahead.
And as much as I love Edgar, and am happy to have him be the stable force that he has been this season, that was such an incredible dick move for him to pull. He litteraly started off the morning publicly encouraging them to kiss with Lindsay. If he's come to this realization, even if he's hoped Jimmy or Gretchen would realize it themselves, dropping that bomb in the manner he did is earth-shattering for anyone. In Jimmy's perception it's as much a betrayal as he previously pulled on Gretchen, which he's only recently come to acknowledge.
I know Edgars been expressing his concern, but two episodes ago he was actively trying to help Jimmy be there for her, if his perceptions in the past 2-3 weeks (show time) have changed so much, I hate to say it, but I think he has to swallow it and let Jimmy and Gretchen take the leap for themselves, but be willing to be there to pick up the pieces if he needs to (just realizing the metaphor back to the broken glass...unintentional).
I kind of dug the Gretchen and her mother moments, because by the time it boils over we (like Gretchen) are hoping to get the carthasis, but her mother is unwilling, or unable, to afford it to her. It wraps up the emotion that much more.
I really don't want Paul and Lindsey back together. I like the space they've been in from the latter half of the previous season through the bachelor/ette party. They love and care about one another, and are respectful to each other willing to help one another out, but they've been through it twice and know that they don't work as a married couple because they can't give each other what they want.
Overall I thought this episode was fantastic. Every scene with Edgar and Jimmy was exquisitely shot, whether it was the montages or the tight shot final discussion. The emotion in Gretchen's scenes were palpable. The comic relief was a bit of a letdown, but nice to see Paul not just cave to Vernon and Becca, and the over the shoulder of the contract was hilarious.
Excited, but nervous as hell for next week.
