She ends up being accepted by the trendy girls in her class, but this puts her friendship with Wendy in danger. Sophie gets a bad bout of flu and wonders what an Earth disease might do to her. The family put her into quarantine. However, she soon learns that ill people get special treatment, and exploits her illness so she will be indulged - even after she's well again.

Josh won't let him - but when Pete gets the flu as well, Brian morphs into Pete and goes to school in his place.
