It's not easy being Agents May. How would you feel if you had an evil person with your face and a robot voice running around with a person that betrayed your team and all of your friends? Agent May won round one with her doppelganger, but in doing so, permanently changed Agent 33's appearance to look like a scarred version of herself. Now that Agent 33 has hooked up with Ward following Whitehall's death, she will definitely be causing Coulson's team more trouble in the future. Like May's showdown with Ward in the Season 1 finale, a fight between these two would be intense - they are almost equals when it comes to fighting skills and the fact that they look almost exactly the same just adds another layer of excitement to the fight. Who will win? May, of course, but it would definitely make things more interesting if 33 was able to win and infiltrate SHIELD next season.
