Abby's responses have been pretty civil from my perspective, and she isn't being too overly defensive. Idk, I'm fresh off a game where she was cult and I find her behavior here to be significantly different. It doesn't seem like the stakes are high for her, which they would be if she was scum. I could be wrong, but I just don't see it. You, on the other hand, seem to be a little flashy in your speech, like saying "I swear I didn't do anything. Read the next sentences where I'll explain why Abby sounds suspicious for me..." and then ultimately following it up with a statement that could easily be discredited if Abby's death is a mislynch. I can't justify trusting you, hence I can't advocate the lynch on Abby regardless of the latter's actual alignment.
