After reading back, AE/LL/MR are not aligned with each other and never scum mates. When MR was pressuring LL, Snake Doctor kinda sniped LL as well, while Lewt and NIK who were around, weren't very committed to either direction. J23 also later comes in snipes MR as well. After page 20, the focus shifts more on me.
Using the LL sus as a magnet, I'd say:
MR - scum lean
AE - town lean
LL - town lean
SD - scum lean
J23 - ?
