If she was an undercover cop she wouldn't be allowed to commit a felony by buying and selling drugs.I just finished my LILY walkthrough. Man... I think there is definitely something more to Lily than just being a stripper at Pink Rose.
The line don't fall for me at end of episode 9 is also quite ominous. The way Lily is getting herself around all the major drug players make her even more suspicious.
Tommy has a thing for her.
She is getting closer and closer to Quinn.
Now she is interacted with Vinny.
So it's either she is just a bad girl with a drug addiction... or there is something else.
Maybe she is an undercover cop, or most likely an informant?
