After an eventful start of the day of finding a scrumptious meal, Moira finally braved the water in the human body, swimming was a little awkward, but she made it over eventually.
She's been on the island for several days now, it's time to explore. The distance didn't seem that far and the water was calm, as if welcoming her to explore, so she took to it right away.
What she hadn't expected was to see someone heading indoors, as if they'd noticed her approach, so being stupidly brave, she went straight for the front door.
Maybe they'd help her get back to her actual body? Explain to her what's going on?
