"I don't think you want me to bore you with the history of playing cards. These look pretty much like a bloated, pointlessly huge Major Arcana. Kind of silly names, too."

"Why, what kind of names do those have?"

"The Chariot, The Tower, The Sun, The Moon...what kind of name is 'The Sweet'?"

"Yeah, I guess so."

He thumbs through the deck, and pulls out a card, showing it to Stiles.

"'The Big' sounds like someone ran out of ideas."

It may not have liked the way Scott's talking about it, because it starts glowing, and then his asthma inhaler starts glowing, and then it's the size of a computer monitor.

"You know, I should go to the woods more often." 

"Maybe we should talk about this! I'm pretty sure that isn't normal. Since when do cards do that?"

"Try saying it again, the name."

"The, uh, 'The Big'?"

The inhaler becomes small again.

"Try another one."

Okay, nothing too weird. 

Here we go.

"The Song, please..."

The card glows, and disappears, and in Scott's room is a young girl in a long dress. She bows slightly then starts singing a beautiful, wordless melody.

"Is your door locked?"

"Even if my mom is worried about the girl in my room, I'm definitely more worried she came from a card!"

He walks closer to the girl. 

"Hello? Can you understand me? I'm Scott."

She stops her singing and dips her head in acknowledgement. "Hello," she sings as if she was going to start singing Lionel Richie's 'Hello' song.

"So she can sing. How descriptive."

"Why did you sing for us?"

She sings a piece of Kirk Whalum's "It's what I do." Specifically the part where it goes "It's what I do."

"...Do you want to?"

She shrugs, and sings the first four words of Regina Spektor's "I want to sing."

"Scott, this is way too cool to have a mental breakdown over. Here, try this one."

He grabs a card at random from the deck.

It's one called 'The Windy.'

"I guess this one makes wind? That should be safe...The Windy, please make some wind."
