Oh yeah no worries, I enjoy bouncing ideas around.
Yeah I wouldn't dismiss it, I just don't think we've uncovered a good enough reason for Victoria to do what she's doing, hence why I also noted that there's a chance the blackmail is hinging on information that we don't have access to, perhaps a shared past event between Ashe and whomever the blackmailer is that lies as an unseen trigger for that character.
And yeah as you said, it's more like a game than conventional blackmail which makes it a bit difficult to pinpoint whom the blackmailer is and why they are blackmailing to begin with.
I did ponder the idea of Victoria potentially doing it to show that Ashe isn't a good fit for Delilah, I think out of all the reasons for Victoria to blackmail, that one makes the most kind of sense in a twisted way. Mainly because we don't really know Victoria or what she's like, so it's absolutely a possibility and gives an adequate reason for Delilah to be involved other than Victoria being a sociopath.
I think a character as wired and apparently into Ashe is a bit of a coinflip in terms of how they would react or do things in that they either take WAY too long to mentally build themselves up and think of plans, or they do things WAY too quickly and rashly. The current blackmail and Delilah's behaviour would fit into the latter where she might have jumped the gun and she isn't really sure where to go with things or what she's doing, and only really thinking that she wants Ashe to turn to her.
I think it's the strongest theory involving Delilah atleast since it would explain her erratic and almost unhinged behaviour a bit better than most I've seen thus far, and it would also fit in with how much she seemingly romanticizes Ashe.
Yeah, I think Fiona is a fairly weak possibility, but it's also one I have a hard time letting go of completely with all the media I've seen/read that involved a best friend blackmailing someone. But yeah it is basically the weakest out of all the 'possible' ones, but given that the blackmail started after Fiona potentially got a handjob, there's always a small possibility that it triggered something with Fiona.
Oh yeah, Moira has the means but that's about it, you pretty much perfectly pointed out why it's not feasible.
If it turns out to be Victoria then hot damn that situation will be complicated going forward.. you're potentially banging her wife, and her daughter is into you to an unhealthy degree and now you're getting blackmailed by that person. That's a LOT of potential drama and potential to blow up several peoples lives.
Rachel would be the worst case scenario, fully DEFCON 1 status and would probably cause me to drop the game.
