All paths lead to white.

The irony is quite strong seeing you chose Sophia, despitequite a number of your posts slurring her.
What I find interesting is that if we do take drugs, Sophia looks at us less favourable (Sophia rapport -2). I'm guessing it's because we were so angry about being drugged before (with aphrodisiac made by her, probably a lot safer than cocaine) but now we're doing coke. Or it might have to do with the fact that we're snorting coke off of Allison's ass and not hers :]. Anyway, I love details like these and TD wasn't kidding when he said that almost every decision we make is flagged.
Yes, the storyline gloves come off. Choices will have consequences. Even if I were not a Sophia fan, I would have taken her path, since Allison and the druggies are the highway to hell.
I don't think that what was happening in the Vault had happened to Sophia, although I guess it is plausible. I won't buy any hypnosis (which finger snap points to) or multiple personality disorder trope either (which "where did that succubus go?" -> "She only comes out when she needs to" points to). She might as well have a twin if we're going down that road, that could lead to an enjoyable sex scene at least. I'm still hoping TD will make all of this in a way I'll buy it but even if not I'm sure it will at least be fun.
You might have read my post above on this topic. I am rather sure what happens in the vault, did not happen to Sophia. Still, I think beside special training she herself confirmed, that
personality imprints play a big role here. Welldone ones since Abel is fond of Sophia and she is his successor, but nevertheless such things are dark black ops and secret services stuff.
So yeah, it seems she was somehow trained/conditioned but I fail to see why visiting Edwin would be something Abel would forbid and why would Sophia want to keep it a secret or Abel make her forget about it.
I theorise it is less that Abel "forbade" visiting the MC, but that she came to apologise(!) for Abel and herself. As explained by Sophia herself, Abel and Chuck are in a mega pissing content with the loser being probably minced meat afterwards. Apologising to Edwin means "showing weakness" which the enemy can see, since Edwin talked with Chuck about the visit. I must fire up a save where Edwin keeps the Abel/Sophia visit under wraps, if that changes some parts.
