"The Devil Within" was the the song featured when Black Widow first appeared, at the end of episode 4X01. S ince it's pretty obvious the producers put a lot of thought when they choose music for PLL, then  that song has so many hidden hints towards her possible identity.

- She might be the lover to the liars' worst nightmare, which means that Uber-A might be also a guy.

- She is after the liars themselves, and she has her own motives and reasons of doing so.

- She's equal to Uber-A, and might be working indepently from him/her.

The more and more I think about it, the more I believe Hanna's twin is The Black Widow and she's working with Uber-A.
