Jedao follows Sharon with mothsense more than with vision, so he recognizes the moment her shape disappears. He doesn't encroach on the fog but waits with his senses alert for what comes out. There's no massive monster or expansion of Otherworld. It only enables Sharon to escape perception, even his senses, for a little while.

He shifts into a rarer form for him: a black squirrel. He runs along the branches through the area Sharon left behind and monitors for shapes. Human and animal because this is Folkmore, and just as he can change shape, Sharon can too. He pitter patters along in the direction of the wildlife he sees. One of them will be suspicious, but he too doesn't approach too brazenly.

He's just a squirrel. An inconspicuous squirrel.
