I didn't post anything in regards to reads about anyone, as I was keeping them to myself. You could see my early slight scumread-gone-vote on Sub as the only tell I let out at that point.
As far as saving you, I thought UTA was bluffing to get focus away from the most talkative member of the game. If you are/were mafia, you wouldn't have died anyway, but talking so much would have given your role away the longer you're alive. As town, you were/are pressing people to get info, which is a useful town skill. I recognize(d) that and chose to make sure if you were town you were safe in case UTA was bluffing.
