Lila as the new villan?

I just started watching season 6 (on episode two). I haven't watched season 5 since it came out so I don't remember if they revealed the new villain, but I distinctly remember it being Lila (however, my memory does suck). Can anyone tell me if I'm right without season 6 spoilers? Also why I might think that it was Lila if I'm wrong. I know I could just go back and watched episodes, but color me lazy, I don't feel like doing that.
