I reread the end of D1 and CTRL+F'd every mention of "Mag" in D2 and to say that before I go in-depth: I'm happy I was recalling it correctly. I was the very first vote on Magoroth on D2 that did not switch off afterwards. So leave it with the "Mayor was buddying Mag", Mike. It's total bullshit and I said so several times.
A longer while after that SB16 was the second person who got onto the Mag lynch as well and SB16 was outspoken about his scumminess. So the association of SB16 being a scum mate of Mag is slim to none.
I'll now post a short list of everyone and the rough associations with Mag they all had:
SB16: As said above, slim to none chance of him being his scum mate.
Brendan: Repeatedly said that Mag is scummy throughout D2. Didn't vote him but was firm in that belief from what I could see.
blink: Early vote on Mag and soft suspicion of him early on in the day but later on sheeped him on SB16. Probably not his scum mate but definitely some kind of neutral role as claimed.
AIVION: Pretty much confirmed town but was weirdly swayed by Mag's proposal :P Ended up hammering Mag though.
Mike: Was in a stand-off with Mag since the beginning so definitely not allied.
Slaol: Didn't even mention Mag once from what I can see. Likely scum mate.
yzb25: Tried to call attention to Mike's possible scumminess but said that Mag was very likely scum when Mag was at L-1. Possible association, it's definitely suspicious. With my knowledge there's only one situation in which yzb would be scum and that's the more unlikely one than the one I currently believe in.
So if I had to pick from this list, from most likely scum mate to least likely it'd be Slaol >>> Brendan == blink > SB16 == yzb == AIVION == Mike in my opinion.
My vote goes out to Slaol.
