If the watcher results are revealed, the following would happen:
Watcher would have 5 names:
Mashley
Himself
Tracker
Motivator
Mafia
This would obviously expose the tracker and motivator. On the other hand, it also confirms four people (KRZY, watcher, tracker, motivator) as town and one person as mafia.
It's unlikely there would be a mislynch. First off, the the mafia can't really fakeclaim his way out of it. If he doesn't claim at all or claims something different, he's obviously mafia. If he claims watcher or tracker, it would be a duplicate claim of the real person, so we'd have it narrowed down to 50%. However, these roles could be easily confirmed the next night, so it would be best not to lynch either one until the next day. Under this scenario, it's likely the mafia would kill the watcher at night because he is the most powerful of the listed roles.
The alternative is to have no one claim and risk the watcher being randomly killed before revealing any information. On the other hand, it would allow the watcher to possibly gather more results while hidden, but tracker and watcher are both difficult roles to actually get useful results out of through luck.
