You're Lisa's younger sibling (3 years apart/she's 19) and both members of Lottie's wellness centre, to seek shelter from your narcissistic mother, but go back there one day to get her pet fish, Gilly the 14th, on the way back from selling honey at the market for Lottie, it was all civilised until things got heated

Mom: "Just because you're both a cult responsibility now, doesn't mean that part of you is gone. You can't take care of yourself now, honey, let alone a fish."

Lisa: "He's a fish!"

Mom: "That you will kill. Not by forgetting to feed it, but by opening your arteries, and leaving it alone to starve."
