We are [siblings] (or any type of relationship you prefer). We had just gotten into a car accident. You came out uninjured, but both our parents are in a very long coma. I've been in a wheelchair, looking after you for over a year at home. However, I've been contacted about a revolutionary new treatment involving a blood transfusion that might help me regain strength to walk,

though it comes with the trade-off of combining my body with a horse (or another creature, if you prefer), altering my appearance. [You could also choose to take the treatment with me as support, but that's optional.]
