Breaking Bad’s girl-next-door couldn’t have been further from the archetype—and we wouldn’t have it any other way. Sweet and approachable aren’t exactly words we'd use to categorize Jesse Pinkman’s (Aaron Paul) smoldering neighbor, Jane (Krysten Ritter), who proved to be more of a "crazy ex" in the trifling sense than the literal as one of the first (but far from the last) characters to drive a stake into his relationship with Walter White (Bryan Cranston).

In addition to bringing some much-appreciated eye candy to the show (no offense, Skyler and Wendy the Prostitute), Ritter also brought danger in the forms of influential heroin speedballing habits and blackmail threats. Still, we could OD on Jane’s Season Two appearances all year long.
