Poor Beau is never free from scruffy wizards. Strange appears in a nearby reflection of one of the water features, during one of the dark cycles when most sensible people would be sleeping. Considering that his sleep schedule is fucked seven ways to Sunday, Strange isn't sensible, and he doesn't really want to fall asleep inside a fae artifact, Strange is awake.

Hopefully Beau's awake as well because she's getting a loud whisper in her ear,

"Psst! Are you awake?"
