Coolio is mentally unstable, that's why he left and he knows it! He picked on Nadia from day one, bullied her and mocked her accent! He enjoyed upsetting her, desperate for a "show", she said all she has in the house are her personal belongings, how dare he, start hiding/damaging them, humiliating Nadia? She is a human being with feelings, too.
They never got on, why should she be fake and act like it's funny!? You would have been angry, too if you were in her shoes, so to speak.
