I don't see her making great contributions science or the arts but she's far from dumb. She's immoral but is a very effective manipulator. Remember she convinced
1) Chris that she wasn't sleeping with Ralph, loved him, and would eventually have kids with him even though they'd never met.
2) Dad that Chris was a psycho stalker rather than someone she was stringing along for shits and giggles.
3) Ralph that Dad beat her and Chris was a stalker, that she was committed to the relationship and was only going to spend a day in DC with her folks, mainly her Mum, when in fact she was going to bail. As soon as she got to DC she gushed about her dear old Dad.
She's manipulated all the men in her life to a remarkable degree, telling them exactly what they need to hear to be on her side and against each other. This sort of behavior is morally extremely questionable but
it has better survival characteristics than doing the right thing.
She could easily convince Dad and potentially a court that she's an exploited innocent rather than a devious schemer with potentially disastrous consequences for Ralph.
Ralph should be shitting himself right now, not from his Makers Mark diet but out of the dire possibility of
ending up in court with Faith as a witness for the prosecution. He probably isn't of course, he'll continue to mouth off at anyone who pisses him off on Twitter encouraged by the odious Masterson. Problem is, that makes his day in court all the more likely.
