We know that August was involved in porn production before, and Edwin even asks his mother if she's heard of that man, but she seems to be unfamiliar with him.
Though if she did she would probably not tell the MC. I am curious where this story will go. The MC's mom heavily suspects even if she doesn't know and I am still extremely suspicious of Kathleen's intentions as she went to talk to the MC's mom...I would not put it beyond that sadistic cunt to drag mom into club some way or another(probably as some kind of guest as this doesn't seem to be the type of game that will have incest) and bring her face to face with her son there. Though now there is also the tape of the MC with Rosalind where she does say his name once too...that will almost certainly come back to bite MC in the ass.
Not sure about anyone else, but I'm hoping to keep the MC's mom away from any of the staff at the club; I don't trust them. For that matter, I'd like to keep her away from the guests too.
I think eventually the MC will have to tell his mom about the club, at least in a broad strokes type of explanation. My hope it that will come as part of the ending, after the MC has managed to get the club shut down. Though he may have to tell her something sooner, if only to keep her out of Chuck and Kat's clutches.
Granted it's a long way off. He still needs to find a way to prove what Chuck and Kat have done to get them ousted. Which will be difficult, both because they are good at covering their tracks, and because, as August has pointed out, there are a number of powerful people, including those in law enforcement, that frequent the club.
By the way, what tape are you talking about? The one from Rosalind's scene at the club? If so, those of us that chose to let Ian have that scene with her don't need to worry about that.
