How do you think the game would have been different if Aestrix hadn't been outed as traitor on Day 1?
If she had been too obvious in the main thread, she would have been nightkilled. Her best hope would be that the people in line to assign the kill ahead of her all die, but only people below her died. Maybe that would have been different if she were alive, though, but again, she wouldn't be able to engineer votes towards jalapeno_dude without everyone in the mafia knowing she's the traitor.
If Keo had established a private chat channel with her, though...
Oh, one suggestion for making future games more fun would be to somehow avoid speculation on whatever roles Alicorn might have given somebody. I have no idea what tipped jalapeno_dude off that Aestrix was the traitor, but I do remember being a little suspicious myself when she said that she had asked Alicorn to give her a role she could have fun with.
