With Snake gone and Spike totally down in the dumps, keeping the household together has fallen totally onto Emma's shoulders. She puts everything she has into looking after Jack, Spike and Manny.
When Manny begs Emma to help her lose weight for an upcoming audition, Emma throws herself into the task.
She has no control in her life: she can't bring Snake home and she can't even date Peter for fear Manny will find out, but she can control what she and Manny eat, and she finds some comfort in that.
Emma thinks she is fat, so she tries to lose the weight. Emma starts exercising and stops eating.
Manny does the same thing, but Emma goes to the extreme. She turns to purging and wants Manny to do the same. Emma gets mad at her, but she keeps on using her weight loss tactic.
Spike found out about the kiss Snake and Ms. Hatzilakos shared. She kicks him out of the house and her life.
Snake tries to win her back by giving her a necklace with her birthstone inside. Spike then throws it away. He doesn't know what to do know, so he goes to Joey's house.
While he is there he asks him about what he should do. But before he could answer, his girlfriend Diane told Snake to make her fall in love with him again.
Joey and Snake exchange wary glances as if they didn't know what she was talking about. So Diane asked him "what made her fall in love with you."
Snake finally won Spike's heart back later that day when he met her in the mall.
