Moomin they all turned on Sophie in series 2. There was lots of bitching then. Series 1, Jess had a hard time on occasion.
Also someone up thread stated Amber had stormed over to Lucie shouting at her about Amy crying, but that isn't how it happened. Lucie joined the girls and was laughing about it in not the nicest of ways, they said twice that Amy was upset it was only then Lucie stopped laughing and also altered her 'getting my anger out somehow' to 'stress-relief'.
We see not even an hour a day, so those saying Amy is 'constantly' talking about Lucie are being a bit dramatic. As someone else said, that could be the only time she mentions her all day. Possibly because she's been told to or someone else has.
Admittedly Amy's face last night was hilarious in how blatant her feelings were. I think she's hurt because in the first week she was supportive of Lucie, who has since pretty much ditched her. She's handling it badly and is acting quite immaturely, that we're seeing anyway.
