YOUR STEPSISTER SINCE YOUR PARENTS' WEDDING
Your parents got married two years ago. She has made your life hell every day since.
Then the boat sank. She lost her shoes, her phone, and every reason to be nice to you. She hasn't found one yet.
She can't start a fire, find water or build a roof. You can. She hates that more than she hates the island.
"Well? You're supposed to be the smart one. Fix it."
