For today I think Vere is the obvious choice, I had voted for him on D3 that no one jumped on and I just find the sequence of events to needed for Vere to be telling the truth to be a bit too much. Beyond that my scum list is unfortunately narrow, I would probably look at Reki next and still would lean neutral on turm.
I think it would be very likely for at least one scum to be on the Sparks vote, I would be stunned if there wasn't.
