S2, E16: Casey's (Spencer Grammer) grand-big sister, Kiki (Collette Wolfe), is back at Cyprus-Rhodes University for her wedding and all the ZBZ girls are invited. Amidst all the wedding frenzy, Max decides it's time to take his relationship with Casey to the next level and gets down on one knee. How will Casey react to Max's bold move? Meanwhile, with Andy (Jesse McCartney) out of town, Jordan (Johanna Braddy) ends up dragging Rusty (Jacob Zachar) around town to help pick up the flowers for Kiki's wedding. When the two discover that the order was never placed, they have to come up with a plan of action -- a plan that backfires and puts both of them in the emergency room with identical allergic reactions. The unexpected common bond leads them to share a kiss. Rebecca (Dilshad Vadsaria), in the meantime, soon finds herself in new territory as she kisses Ashleigh's openly gay big sis, Robin (Anna Osceola), in one of the bachelorette party game - sparking Rebecca's curiosity.
