The duty of a town is too lynch out any suspects ( While keeping a low profile so as to avoid getting killed ) and Xander definitely isn't following the above protocol. He does have a history ( From the one game he's played ) to keep a low profile though he's way more active in this game, is it maybe because the stakes are much higher for his cause?
While the objective of town is to lynch, the duty of the town is to create discussion. Duty as a townsperson is to talk and get people engaged and talking. While this isn't necessarily a tell of any player, him NOT pushing a random vote train with an easily excusable "boredom" play comes off as supportive to town's strength, ie; to allow for discussion. I could also point out that he made a "lynch setup comment" earlier in the day:
"He still hasn't showed up?"
While the grammar is poor :D, posting this comment earlier would have been easy reinforcement for a follow-up vote when spurge made his initial vote. He could have just voted and said, "see here, I was already concerned about prof's absence, I'm not just blindly following a bandwagon vote".
And again, my analysis of him comes regardless of my own alignment.
So I'm just going to re-iterate the slight town read on him, and slight only because there's the off chance that he's simply putting in work to seem town later.
The only thing keeping that from strong town read is whether or not I think xander is capable in his limited experience to make such a play.
