For us it was probably SheShe's Lock-Merge. It was pretty awesome though it was pretty weird for Joy and Darlene to just do that on their own. Seems like that should have required a discussion first. Though it was pretty obvious that SheShe was Darlene's new form/name considering she talked about wanting to change that for a year and even described SheShe long before. Of course it was also weird that SheShe told bear straight up that she was Darlene like so many times and he didn't get it for a year.
