Katie and Emily

Plot:

Since Katie won't leave the house, Emily impersonates her to take her exam and meets Naomi, who tells her that she is going to Cyprus for the summer but declines Emily's invitation to accompany her to the end-of-term ball, though she does turn up on her own. At the ball, the sisters fight when Katie learns that Emily went with JJ, but Emily resists the temptation to hit her sister, instead declaring her love for Naomi and walking off with her. Pandora and Thomas are also able to get it together.
