Kay was memorizing his monologue. The reason he was doing so in the actual theater, rather than in his house was because Arthur was still there, probably watching his favorite vampire show, Bonnie the Cranberry Player, or whatever it was called. Gaston was also there and Kay didn't want to think about he was doing. Actually, he did, but his imagination often came up with Gastonian activities more disturbing than the real man did. Point being, he was sick of being told to stop rambling on about kings who got their eyes poked out because bind men told them so -- and later that even his thoroughly unappreciative audience knew that Oedipus Rex did NOT have sex with chickens, as Kay seemed to think when he practiced his monologues. So that's why he was there, long story short.
Because Kay was severely ADHD, he soon grew bored of doing his homework, so he progressed (or would it be degressed?) to procrastination. Flipping to an empty page in his notebook, he picked up his quill and began to write, singing it to himself as he wrote:
"When you wish upon a w.hore, Forget not the prostitution lore, Remember that they come at night, And won't put up a fight."
Giselle had been wandering because sometimes wandering was just so lovely. And it was also a way to meet some very lovely people. And new friends, whether they be human or not. In fact Giselle had made friends with a very friendly little butterfly and she was talking to it as she walked along, not even paying attention to where she was going.
“You see, that’s why true love is wonderful,” she told the butterfly as it floated along beside her. “And I really can’t wait for Edward to get here. It will be wonderful. And then we’ll share true love’s first kiss and he’ll take me back to Andalasia and we’ll live happily ever after.” She sighed thinking about how wonderful happily ever after would be once they got there.
And in that moment of quiet Giselle heard a voice. It was a very lovely voice too and it was singing. So she followed the voice until she found the young man to whom the voice belonged. She clapped enthusiastically when he finished singing. “That was lovely,” she said, sashaying towards him. “You sing very nicely.”
