Submitted Prompt #39

Co-Host A has been somehow transported into the body of Teen B, whose family is much, much different from theirs. The rest of their system is nowhere to be found. They're already used to masking in strange situations, so they try their best to go with the flow. They wouldn't want Teen B to come back to a ruined house that thinks they're crazy, hm? So they remain calm, thinking through causes and solutions for body swapping, and try to mask as best they can.

... Until Teen B's mom starts using magic, and they realize everyone in this strange little family has damn near reality bending powers. Including themself – although they have no clue how to use them!

Write about Co-Host A trying not to "break character" as the rest of the family keeps doing these mind-blowing feats – all while they're trying to figure out the spell to get home.
