I don’t believe for a second that she really had Noel break in to prove a point. I think she is genuinely scared and knew it was A. I think she could tell the girls were so scare and this A is intense, so she lied about it. She wants to calm them down, even if they will be pissed. Next week’s episode her lies are suppose to tangle so maybe the girls will figure it out.
Anyway, I think it really was A and the A at the stable was really A, hence an A team.
