It's because she has a messenger ability that she was able to tell us this when she was silenced. Silencing would deter her from posting, not using her ability.
I have no idea. Weird combination to have an announcer ability and a lie detect.
I have no idea what you mean here? Do you mean her saying her results are either True, partially true, or false? I don't think she has to claim all that if her result is already False.
You mean when there was a lie detect when she used it on Ripped right? I have no idea. I don't think Xlaw announced it. Maybe yours and Cray Cray's theory of her faking the lie detect with her announcer ability is possible.
Because Flower has an announcer ability and Ekko and anon don't.
