she seems 2 be going a bit mad with the imagining melissa etc .. but the wave to melissa in the final scene could signify she gets better as she's saying 'goodbye' 2 melissa.
Yeah I thought that she was waving goodbye to Melissa for good as she seemed ok with Sarah and Nancy, liked they'd made up but I think she's got a long way to go
Oh i took it to mean that even though she'd had the chat with sarah and Nancy - Meliisa was still there, which meant nothing had actually chnaged. I thought it was so powerful that Melissa's spirit was with Hannah - it's like the voice of her anorexia and i cried so much!! It shows it's such a waste of a young life and Hannah hasn't really thought that Melissa died because of what they had been doing.
