Commentary
- Elliot transformed before sleep (also Tedd in case it was missed)
This is just me musing, this isn't official canon, but!
I'm considering the possibility that Grace's antennae still sense her surroundings to some degree while sleeping. Just like a loud enough noise could wake us up, a silent, unfamiliar presence could be sensed by Grace and wake her up.
I'm considering this because I think it would also allow Grace to navigate to some degree while sleeping. Not perfectly, but enough to avoid hazards and falling off of things (and possibly finding Ellens).
I also propose the simple explanation that Grace wound up over there due to what side she was sleeping on. She was simply facing towards Ellen, sensed a familiar presence, and made like a sleepy hedgehog to get over there.
Again, however, none of that is definite canon, and I'm not the boss of you if you have different conclusions.
