a becky lynch heel turn

This is another option, especially if Charlotte is directly involved in the decision of the match. Maybe she wins. Maybe she gets pinned by Carmella. Either way, Becky Lynch loses, and the opportunity that was supposed to be hers and hers alone is now gone. It’s enough to make anyone snap.
Lynch, tired of being second place and playing second fiddle to Charlotte, decides to take out her frustrations through violence. It would be like that time when Batista was upset that he couldn’t become champion again, so he attacked Rey Mysterio.
As much sense as this makes, I’m not exactly in favor of it. Becky Lynch is easily the most likable character in the Smackdown Women’s Division, Turning her makes no sense, especially when she has a right to feel upset. It’s all backwards.
Still, it’ll be exciting to see where this thing goes, so I’ll be keeping tabs on the story.
