"I come from another realm inhabited entirely by sentient horses," Ms. Tomlin explained which surprised both of us.
"What, like My Little Pony or something?" Lindsey asked.
"Something like that," Ms. Tomlin said with a shake of her head. "But we've had a bit of a problem lately, there was a great war that killed off most of our stallions. So I was sent here to bring more horses to my world, but since your world's horses aren't sentient..."
"You're turning humans into horses?" I said, looking at her strangely. "Exactly how is that going to work?"
"You can change between your human and horse forms at will in this universe, at least once you learn how," Ms. Tomlin said. "What I used on you can spread from person to person by contact."
You looked at Lindsey and honestly you had no idea what to say to that. She actually wanted you both to start turning people into horses? Or did you not really have a choice?
"Is it reversible?" Lindsey asked.
"No, its permanent," Ms. Tomlin said. "But I can always do something to help you. I can either make it so you only remember being a horse that can turn into a human, or you can go to my world and spend the rest of your days there. What will you choose?"
