Ok...so, Neil says in the first "episode", "so, MC is into sharing eh?" to himself, after learning that from the psycho,,err, the counselor.
Given that "sharing" cannot involve "cheating", in my view, and I assume others too? Is that your understanding?
It can't just be a matter of avoidance...
So, Neil's character will have to be a consensual partner? Whereby, he is merely placing himself as a possible sharing "opportunity" to Sarah and Alex???? With no skulduggery involved? Quite a lot of alternate dialogues, huh?
