Yes, she lied at first and never came clean on why she said so in the first place. There is that time where she told the MC not to ask more questions, because doing so would have required her to lie or to admit she's a lesbian. It's not like she was interrupted every time, she had opportunities.
But still, I'm personally not mad at her, I understand where she's comming from. But I see why some people could be mad at her.
Quinn has a very domineering attitude, Camilla is very submisive. I don't think they are alike in any way.
Camila could be an interesting character if given more background, but I don't think she's like Quinn.
Lilia, from Amour Angels.
And yeah, she does look alike
There are many kinds of proof. Camila and Mona's mothers were there when they asked for his underwear. Maybe they followed them. Maybe they took a photo of them naked on a bathroom with cum. I mean, you don't have to have a video tape of the whole thing
Another thing to consider is that Josy namedroprs her stepmother (Tommy's mother) a lot. I'm pretty sure she has to be relevant.
