I agree that she is not exactly a great witness to events, but I doubt her word alone is going to what takes the Ralphamale down. I suspect it will be what she says, his texts, maybe the livestream and if they really want to go for it, they could ask for website records from what Ethan used to contact the halfway cuck guy (His name escapes me). It's been a while but he contacted him on youtube in the livestream and also on Instagram? I don't know how easy it would be to get records from Alphabet and Zuckerberg for such a petty thing, so maybe that isn't possible?
Still the information is there to fuck him either way in my opinion, without relying on Faith whatsoever.
