My guess is you just have to interact with her once, I assume any interaction will work for you to get that option, I also dont think that the stats matter I was just giving you the exact path that I took.Thanks,
For that to happen, do you know if I have to transform her every time and/or "confront her with the evidence"? Also, I didnt have that high stats either.
I dont think confronting Britney with the evidence will count as you interacting with Stacy.
