April plans a party and obnoxiously leaves Ann off the guest list, leading to a confrontation when Leslie refuses to attend without her best girlfriend in tow. Meanwhile, we’re treated to a 3-episode arc in which Tom Haverford tries to play peacemaker between the two women by orchestrating a series of awkward lunches. Donna stays out of it because she’s “above the drama” and focuses on shamelessly promoting the launch of her new wine brand.
As Penny and Amy help Bernadette plan the geeky wedding of the century, Sheldon stirs up drama when he makes a rude comment about how he doesn’t think Penny would be caught dead in an orphanage in South Africa. Amy “tries not to get in the middle” of the fight between her bestie and her boytoy, then Bernadette flips a table and tells her she should “learn to control her man.”
