Lily wasn't wrong.
In my re-watch of season 4, I don't understand how they were trying to paint Lily as the bad person with the Ben situation. Her daughter was a minor, who spent quite her fair share of alone time with her teacher. He took her out of state without permission from the school or a parent. Once he's out of prison, he just gives me the ick. This whole storyline literally gives grooming. Honestly the only bad thing she did was the whole forgery thing.
