so who has Arthur's eyelids? either answer is funny.
1. John does. John is canonically aware and active while Arthur's asleep/unconscious. So who wants to take a shift in the coma ward with the otherwise unresponsive patient whose eyes are open and keep following you around the room?
2. Arthur does. If John pisses him off too much, he can at his discretion say "okay well now NOBODY gets to use the eyes" and close them.
