She's told us outright she's a daddy's girl... If she gets into trouble at some point (likely given the drugs, prostitution, and possible set up for a job at the Pink Rose), think she wouldn't spill Tommy's part in all of it to deflect some of the blame from her? I think that behavior's pretty well in keeping with what we know of her character so far.
And yes, Tommy said ruining his fun.. but it's not like he's going to spill the beans regarding the sex ring, drugs, etc., in the open like that. Yes, maybe some of the DIKs know about it, but I get the distinct impression Rusty doesn't based on the later conversation we see with Tommy & Quinn.
