My general thinking with being outed was that lloyd is mafia role blocker and would figure from the skits that they were blocked and probably by mail keeper and use the same info I did to realize it's me.

As for if I'd stayed quiet, maybe I didn't make it as obvious as I thought and was just being paranoid about them figuring it out from the things I've said, but it seemed pretty likely they knew anyway the same way I knew lloyd was time blocker so no sense dying with what little I know and my skit kept to myself.
