So there's two mysteries to solve with the claims as they stand:
1. Datisi's roleblock on Aaron did not stop Icon's track/follow from giving a result, but Aaron still received NO RESULT. There would still need to be something in play such as a rolestopper or Alien targeting emps/Micc
or me being ascetic
.
2. AaronFrost was nightkilled through Slaxx using a rolestop on him. There would need to be a Strongman or a blocking ability used on Slaxx.
So yes, the easy solution is Slaxx lying. His slot actually rolestopped emps/Micc N1 and didn't rolestop AaronFrost. That N1 action would make sense for scum as emps/Micc was most likely place for a Cop to land, and scum were possibly informed that a Cop exists by way of Chemist. Moving Slaxx to scum also shifts the balance of power to be reasonable. maybe not balanced, but reasonable.
Brainstorming other solutions:
1. Scum have a non-slaxx rolestopper or Alien who targeted emps/Micc N1. They also have a strongman or blocking ability which was used on Slaxx. This makes sense again because emps/micc is a good place for a scum rolestop or alien to land, also that Slaxx's soft claim made it clear he needed to be blocked N2 to get the kill through. They would have had to table the rolestop/alien action N2 in order to make a nightkill unless multitasking was in play. All of these possible scum actions could manifest themselves as a JOAT also.
2.
emps/micc is ascetic and scum have a strongman or blocking ability which was used on Slaxx.
This is crossed out because I'm not ascetic.
3. One or both of Icon/Datisi are lying about their claim. Datisi lying, but Icon town is basically impossible on account of Datisi's N2 roleblock not being used for shenanigans. Icon lying but Datisi town, is possible but unlikely for the non-mechanical reasons.
i'm not done brainstorming yet but have to step away for a bit and am posting incomplete so that my garbage laptop doesn't eat my post while i'm gone.
