I doubt Seymour is Lena's father.
First of all, I think it's too big a cliché. It's such a cheap soap opera trope, and I think and hope Eva won't go for so obvious (and in my view lazy) narrative choices.
Secondly, Lena points out to Ian that she's seen pictures of him. Those are old, but still. I think it would be very unrealistic that she wouldn't have recognized him, at least by now.
Third: GGGB was to a large extent based on porn fantasies, ORS is more realistic. For obvious reasons incest is among the porn fantasies that don't work as well in a realistic scenario.
Aaand fourth: There's already been quite a bit of sexualised content between Lena and Seymour. To then reveal later that he is her biological father, would be a pretty big turn-off for those who don't like incest content.
Still, I admit there's a Chekhov's gun lying around that I assume Eva will use in some way. (Do I have any alternative theories about how? Nope, none at all.)
if lena's current father is a step father, and we don't know who her biological dad is... and dashole is involved in the game... then it means there is a possibility lena will get double penetrated by her two daddy's; her real dad and her step dad.
how do you top what happened in good girl gone bad? with 1 dad?
easy... two dads at the same time.
Dashole isn't involved in the game. They just made some fan art.
