Twilight trotted downstairs. She was somewhat hungry, but figured she ought to get everypony's sight back first, so that she could tell Spike to make her breakfast. She could hear Spike sweeping the floor, so she called out to him.
"Spike, hey, Spike," she called out to him, "Come over here!"
Spike kept sweeping. Insubordination. "I can hear you just fine, Twilight. What is it?"
"Find my book of ocular magic for me, so I can reverse this blindness, so that you can make us some breakfast," Twilight ordered.
"I can't do that, Twilight..."
"And why in Equestria not?" Twilight asked.
"I can't see anything. I can't see any of the books."
"Well, how are you sweeping the floors, then?"
"Probably not very well," Spike admitted. "I'm kind of just guessing where the dirt might be." He continued randomly sweeping.
Twilight sighed. Looks like she was going to have to find that book herself. She rolled up her metaphorical sleeves and went to work.
