Just because she liked some comment and the person is freaking out about it? I don't know... So what about her mum then? Has she died? I mean i would like to see her return to the show, but i don't see any real sign for that at the moment. Maybe she just likes that thought, that things would still be "normal", that her mum wasn't sick and therefore she would still be on the show. Who wouldn't in her case?
