Hannah, Sarah and Nancy

Hannah struggles to get into a dress, and imagines Melissa (who's looking healthy again) is there with her. Hannah knows she's going crazy but likes having Melissa to talk with. Melissa tells her they'll use what happened to her to make Hannah eat again. Hannah says she won't let them.

Suzanne promises Hannah they'll get through this. When she leaves, Hannah starts sobbing.

Suzanne asks Sarah and Nancy to come over. They can't believe Melissa had a heart attack at only 22. They wonder if drugs caused it. She tells them that Hannah doesn't have pneumonia: she's anorexic.

Sarah and Nancy try to talk Hannah into getting some help but Hannah's mad at Sarah and Nancy for not being there for her and says Melissa was the only one who was there for her, her one true friend. She tells them to go to hell. They can't believe they didn't notice.

Later, she opens up more to them but refuses to admit she's anorexic. She tells them stories from her childhood and how she feels distant from Nancy and Sarah and couldn't tell them about how ugly she felt, how her heart was broken over John Paul, how weak she is compared to them. She tells them about the first time she threw up her food, how Melissa showed her how to do it properly, how Melissa didn't judge her.

Sarah says unconditional friendship isn't possible, she just wants a friend to tell her what she's doing ok and that's not real friendship. Sarah tells her she's starving herself to death and loves her to much to have her end up like her. They both cry and hug.

Later, Hannah waves goodbye to Melissa.

Leo and Sasha

Sasha asks her dad who Valerie is when she calls him but he's cagey about it and she gets more suspicious.

Valerie knocks on Leo's door but he just hides and doesn't open the door. Later, Valeria smashes the window and says she's off on holiday to Greece and is leaving the kids.

Sasha is totally confused: she suddenly finds out she has a half brother and sister, Danny and Lauren!

Fletch and Sasha

At school, Fletch is in Sasha's bad books. He keeps apologising and asking her to be his friend again.
