Gemma is clearly just picking on Christopher now because she percieves him as weaker.
She wouldn't dare say anything to Tiffany as she knows Tiffany will take her down.
Gemma can easily bitch and talk about others giving but she can't take it.
She's a bully.
I'm happy Daniella went in to make sure Chris would be okay.

Most people who bitch to others because 'they're just being real' can't take a bit of 'reality' being dosed out to them.

Gemma does strike me as something of a bully. She has made John cry and picked row with many people. Also she clearly wanted rid of Angie

But how much of a drip is Christopher. Panicking like that because she asked to speak to him.
Why doesn't her just do what she says she likes, and be up front and get over it, so say "yes you are a shallow cow, luv ya."
