When I voiced my concern about being seen as tied to Edelgard, those were for the most part not genuine concerns, but rather a tactic. My intention was
1. Get Edelgard targeted before me [and not as a split vote] so that we would know where to play our idols, and
2. Tank my own threat level by dumping all the heat I got for my moves on her.
I am now seeing that it may have worked a little too well, as I'm getting many questions asking why I didn't cut her if I saw her as my shield. I didn't realize that calling Edelgard a shield as a tactic to get her targeted without really meaning it meant I would later be obligated to cut her. If everyone in the game goes home before me there aren't enough rounds to cut everybody!!!
I also wasn't expecting Dorothea and Edelgard to cooperate and vote for Ashe, but they went and did it. I don't know why Edelgard thought that was a good move, that will be for her to explain. I felt that Dorothea would be the best vote for me to make in F4 because she was more likely than Ashe or Edelgard to have votes locked in for her (see: Hapi's question thread).
I feel like taking Edelgard to the finals was not a mistake because even though I set her up to go home before me by calling her a shield, I still think I can beat her in the end! And setting her up to go home before me in a worst case scenario was supposed to be a resume move for me, not her!
The other reason I think that I can beat her is because I believe I was the more active member of our duo that made moves and pushed for votes, while Edelgard was the one telling me to just chill and keep on sliding through as the "mafia informed minority" as she puts it with our idols in tow. I think a difference between us is that having an idol emboldened me to take greater risks, whereas it seemed to do the opposite to Edelgard. I'm not 100% on that read though, but it just felt that way from our conversations.
