She seems to be getting deeper and deeper into the emotional mire, especially now that Alice has revealed the results of her internet search into Carl's background. There doesn't seem to be anyone who can pull her up and make her snap out of her 'I hate Usha' mood. Maybe a change of scriptwriter might help!
Amy doesn't seem to know what she does want. First she threw a hissy fit because she thought that Usha implied that she would attach herself to a married man, and now she's actively chasing the guy! Have the script writers got it wrong?
