Unrealistic with Dylan but realistic with Ellie. Come on.It's true, what's going on with Dylan is completely unrealistic & unbelieveable. If you're really drunk, you still "hit the nail on the head." Dylan's behaviour with Sophia has in no way been calculated to elicit erotic feelings in any woman, let alone his own mother. Sophia would have made an appointment for him with a reputable psychiatrist, if only on the basis of wanting him to grow up well-adjusted sexually & not maybe store up problems for his life moving forwards. If I was into incest, I would have to rationalise that Sophia herself was subconsciously willing for it to happen. Sophia's monologues in the game appear to indicate that it is the expanation the Dev has chosen.
As for beating up Aiden, while that might be very satisfying for Dylan (& all the Aiden haters), it would not solve the problem but could well make it worse. Aiden, or at least his uncle, are within the same social strata as Dylan's family but that doesn't preclude the use of underworld contacts. Any hasty action from a freshly trained Dylan, would IMO escalate matters in ways that might not be predictable but would always be bad.
I'm playing lesbian, but you know, like let them warm up a little or two guys go whoring and the one with the biggest dick leaves the other to fuck first, to warm the bitch up.
