Andrew was not-Mafia in my eyes and I never understood everyone else's scumread on him. I think Axxle killed Andrew because he knew that the SK (Faust) would kill me because he would be lynched the next day if he didn't (Since I'd cop him) and/or he knew my DeDo was a 1-shot Commuter (which he stated previously made the most sense).
Assuming the human child would be comfortable leaving killing you to the SK, which I am not sure of, Axxle or DD would want to kill me, not Andrew. Andrew would have been a mislynch possibility and would have provided some cover by being another suspect.
But I don't think they would leave the kill to the SK. If we have two independent killers, with the human child on the wagon, then he wouldn't have known if faust was SK or not. In case faust was town, the child would have to kill you to keep faust as a suspect, or kill me to still only have 1 IC to deal with.
It also doesn't make sense that Axxle would assume his guess about the door was right, and be confident that you hadn't used it.
