April's great idea to avoid coatroom sex is for Jackson to bring a date, so that his focus will be on that person. He suggests, like a mature adult, that they could choose to focus on the bride and groom instead. But she is wearing a tight strapless dress, which means she'll be naked on the top 20% or so of her body, and apparently has reached age 30 with only one single wedding-appropriate dress so she can't wear something else. Jackson seems to finally think she has a point (and also finds her weird for her single dressy dress) but he's not sure how to find a date with one day's notice. Thank goodness the hospital is full of attractive young people, then; April sees Stephanie and yells out an invitation to her. Jackson tries to stop her but April presses on and Stephanie is so gobsmacked that she can barely form words. With one last reminder about her dress, Jackson caves and tells Stephanie he'll pick her up at 1 in the locker room. But as revenge, he tells April he gets to find her a date and just at that moment, an unsuspecting Smash comes walking down the stairs.
Lizzie is appalled to learn that she has stumpy calves, and Mere is quick to assure her that as calves go, they are fine -- they just don't have quite enough nerve. Mere is there to secretly tell Lizzie about what is going on after Derek refused to ask her, and Lizzie is of course fine to go ahead and give some nerve from each leg. But when Mere asks her not to tell Derek that it was she who approached Lizzie, Lizzie can't take it anymore and tells Mere she's got some balls. Mere seems to deliberately try to misunderstand and pretends Lizzie thinks it might be too much to ask after all but that's not it -- Lizzie is mad that there was no wedding, there was no invite to meet Zola, there was no accepting the family's invitation to visit, and in fact were only ever a couple of pictures sent to the Shepherd family of the newest addition. But yet Derek needs a nerve, and here Mere is. Lizzie has to explain that this is what sisters do for each other but if Mere wants to be a sister, she needs to actually act like one. Finally, Mere falls back on the old reliable excuse of her own shitty family growing up and she doesn't know how to have a family, waaaah. Lizzie brings up Lexie but Mere has no interest in talking about the sister she did actually love and shuts down any more talk of family (especially the reminder that Zola is a part of the big crazy Shepherd family) before she runs off.
