Spleen

Laurence was transformed by the forest wanderer, Ikkit, deep within a cave network. Laurence had been several things: an uncle, a photographer, a trans man, a student, a camper, a human. He was also stubborn to the last, playing Ikkit's games until he couldn't hope to get out with or without the help of the wanderer.
He remembers his previous life in broad strokes, but has trouble finding the specific names and places of those he might wish to look for. The places where people should be are not the places where they are.
When introducing himself as an esk, he finds himself instinctively saying "Spleen" rather than "Laurence" some of the time. Last words can stick with a ghost, and the fall in the cave left him worrying about his organs.
