Bachelorette: Harley and Ivy have drunk sex, Ivy immediately regrets it, ends things with Harley

Dye Hard: Ivy is still going forward with the wedding by picking up the dress she's gonna wear, while Harley deals with the reappearance of Joker

Lovers Quarrel: Ivy finally tells Kiteman about the time she kissed Harley and the time she had sex with her back at the bachelorette, they fight, discuss, buy at the end work through it. Harley deals with the upcoming wedding in her own way by destroying stuff

Something Green, Something Burrowed/ The Runaway Bridesmaid: Harley can't deal with her pent up feelings anymore. At the wedding Harley finally confesses her feelings for Ivy. Ivy accepts that Harley loves her, and Ivy finally comes to terms with her own feelings for Harley.

So that's how I think is gonna be from now on... It's makes sense if you think about it.
