Played by: Laura Prepon
Rap Sheet: Piper's drug-smuggling ex-girlfriend whose testimony led to Piper's arrest.
On the Outside: Prepon originally auditioned for Piper, but Kohan thought she was ''too strong'' for the character, and Prepon herself realized she was wrong for the role. ''I didn't care I just wanted to meet Jenji [Kohan, the show's creator],'' she recalls. ''Reading was the cherry on top.''
Coming Up: While Alex appears in just a handful of episodes including the premiere this season, Prepon promises they deliver: ''Whenever you think we're going one way, we definitely go another.''
