"Wait, what?" Tony asks, both eyebrows raising. "Tear it up?" He adds, then opens the case again and pulls out the card. After a moment of hesitation--he doesn't want to ruin a perfectly good deck of cards, right?--he tears up the card into little pieces. Then he puts the pieces into the box and digs around in his drawer for some rubber bands. "Okay."
This is actually quite fun. Tony smirks as he puts the rubber bands around the box. "...I just hope I remember what card it was." Teasing, of course he does.
