Rhea seems town as per our interactions with her within Blue rose. She was really contributing to the discussion and was open with her reads.
So I don't think she is jester. Also, she said that today she will be going out with family so will be busy. I am town reading her.
Also, Blue rose decided to go after Tac and flower coz these two stood out as scum most to us. Our intention was to see how they will react and go after them if they don't clear themselves as town (Still waiting for flowa response and still not feeling good about TAC).
