He does not. There's a way to structure cease and desist letters so that privacy is still intact but still push forward the essence of the letter. It's only after official legal proceedings begin that he could become aware of our legal names. Not preferred but hopefully the warning letter has some effect.
Update: He just messaged me "you know she begged me to cum in her, right? Remember that next Father's Day."
Lana has suggested she call him and tell him that I've known the whole time, but I feel like it'll just further antagonize him and the best course of action is to just let it be for now and let any communication go through the legal process.
