Mafia 21.

Plessi's positive status allows us to suspect him of aiding the killers, especially when considering his night actions.

Ahem, it's actually quite easy to figure out my role because:
1) I wasn't blocked.
2) My night action was every night.
3) Positive status.
4) Repeated hints, and quite obvious ones at that.

Basically, Captain is subtly hinting that I'm Town.
