I dont have a solid read, so can be persuaded either way by people who know them better (This is different from n insofar that i have no idea rather than just arriving at a neutral verdict):
Contrainer (i have some silly reasons to believe he's town, mostly due to his naivety)
Sherlock Holmes (straight null to me)
I wanted to write out reasoning for all of these, but I'm falling asleep.
Be back in about 5 hours, will answer questions about the reads then if you want.
