Just waded through all of D1 looking for the catalyst of Pie's wagon. Couldn't find one. The notable votes were essentially Oro, who voted first, drafer, who was second but long after oro, and lunatic, who hammered.
Willing to bet at least one of the wolves is on the pie wagon
[pie (6/6): oro, supa, drafter, ragnar, grey, lunatic]
Obviously not oro, I still think grey is town.
One or both is within {ragnar, lunatic, drafter, supa}
