What made me laugh about Ekin Su's strop was how she ranted on about not wanting to be judged - yet she's come on a show where you're always at risk of being nommed. And that's what she counts as 'being judged'. Duh.
I think what Marisha was doing in her nomination was similar to what we all do in, say, a job interview where you're asked about your weak spots and have to make something negative sound positive. Doubt it was the 'real' reason but a ham-fisted attempt at a compliment - 'You're sure to win'. So that went well.
I can imagine E-S's ex Davide sitting on his sofa watching and quietly going, 'You see?'
