[this is a SUPER BRIGHT GRIN, Kaito loves showing off his magic. The flower goes back in his palm, where he coves it with both hands. After a few seconds, he removes his hand again to show that the flower has mysteriously been transformed into a deck of cards!

Which he proceeds to shuffle. He's not done there it seems. After a few moments of this, he flicks one card from the top of the deck and shows it to Naminé (The Queen of Hearts). He turns the card over to show her the back of the same card, then flips it over to show her the face again. Voila! No more Queen of Hearts, but now a Jack of Spades!]
