Ohh ok, I did basically all of that, except I did tell Claire she was fat. Hated doing it, but I thought I had to do it in order to lock her route out. Thanks for the help!
I absolutely will as soon as I figure it out, ha ha. I'm trying different combinations with the conversations to try and "balance" it so I don't end up locked in one, but for some reason, it still gives me Rose every time. Its very subtle, difficult to determine which stuff is really impactful and what isn't and how.
