Regarding the first one, I am guessing either she was artificially created using the Staff of Rejection (which would explain the robotic arm), or maybe a friend/relative of Waluigi. Both of those were used as plot twists for Rei in NGE, whom Tari seems to take inspiration from.

Regarding the second one, I think that was just to keep the act up. Method acting is surprisingly effective for getting you to act in a highly specific way.

Regarding the third one, I think that Tari is either a full-on villain pretending to be a hero, or an anti-villain who DOES have some form of shyness, but is exaggerating it because Waluigi told her to.

But that's just my take on things. I could be totally wrong though. We'll just have to wait until tomorrow.
