On RAW, Emmalina made her long-awaited debut but then to the surprise of everyone, she noted that the makeover from Emma to Emmalina was complete and now the makeover from Emmalina back to Emma would begin. This seemingly dropped the whole storyline.
According to Pro Wrestling Sheet, this whole gimmick was an attempt to make Emma into a diva character from the past who was all looks and no in-ring talent. That has been dropped because of a rumour that officials didn't feel like Emma was fully committed to the part but they apparently still want to try it on another talent.
Personal note: How about trying it on someone that we haven't seen wrestle and is quite good at it? Lunacy!
