Yes. Alienation of Affection is pretty much done. Only available in a few states.
On another note, while I'm sure BellLA law will provide differently, and we can never underestimate Eric's romantic stupidity, there are no "cleaners" to which Quinn can take Eric. Evn if he didn't get her to sign a prenup, at most, she'd be entitled to half of the money he made/net worth that he acquired during the marriage. So, if he'd been worth $500M the day they married and $501M the day they separated, she'd get half of $1M. Again, there'll likely be some cockamamie nonsense where she gets share
