Sleep
Fiyero found that being made of straw meant sleep was no longer a necessity for him. He could sleep, if he really wanted to, but he got no pleasure from it.
Elphaba, though she still required it, hated sleeping – it was when she felt the most vulnerable and unguarded. But with Fiyero she allowed herself to relax. She would curl up next to him, head tucked into his shoulder, arm draped over his chest. He sometimes jokingly accused her of only keeping him around to use as a pillow.
He greatly preferred watching over her to getting any sleep himself.
