He floats over toward Theo. "You really don't know?"

"Know what? Because I know lots of things, but what the 'Clow Cards' are isn't one of them." (Or maybe it is, but he's not willing to give information without getting some first.)

He slowly moves over to his bed for no obvious reason.

He sighs and sits on the bed. "I woke up in this museum and the Book was open and all the Clow Cards were gone. I tried to find them and could only sense Windy but it's not here..."

"You woke up in a museum? What were you doing before that, and what do you mean you could 'sense Windy'?"

He stops before he gets to the bed, still maintaining some distance from Cerberus. Still somewhat wary, he hasn't put the book down, but fortunately it doesn't seem he'll need to attack.

"...I was actually supposed to be guarding the cards but I... fell asleep."

"... Oh." – that's not really what he was expecting. "So why'd you come here?"

He's starting to feel a little sympathetic towards this creature.

"I told you, I was looking for the cards! If the Clow Cards aren't all collected and sealed again, a great catastrophe will befall the world!"

"A great catastrophe? Can you be more specific? And why were you looking here for the cards? Did you 'sense Windy' and come here?"

Yeah, perhaps "hostile and withholding information" wasn't the best way to go about this. In fairness: weird creature, at night, after a weird day.

"I—" His ears twitch, and he looks around.

Theo looks suspiciously at the bear, then looks around as well. "What?"

"I am still sensing Windy here. It's not usually this quiet."

"Quiet? Didn't you say it was a card...? Or is it... special; like, have I mentioned that you're a winged, talking bear? You do know that, right?"

Cerberus inches his way in the general direction of Theo's pillow.

Theo runs over to the pillow, attempting to block Cerberus from reaching it.

"You have it!" Cerberus accuses.

He grabs hold of the card, stands up, and holds the book at the ready again. "Yeah, I do, but how do I know you're who you say you are? Even if there is a 'Guardian of the Clow Cards', how do I know you're them?"

"You were the one who scattered them! Why should I trust you to have it?"

"I didn't scatter them, I stood near a book and then touched a card! How should I know that'd scatter some magical cards? Magical cards don't exist!"

"You're holding one! And now you've brought catastrophe into the world!"

"Well obviously they do exist, but they didn't, not when I was in that museum, at least not as far as I knew! And it's not my fault that they cause catastrophe!"

"But it's your fault they've been released, and you keep being so unhelpful!"

"Well maybe we should stop shouting at each other and try to–" He's interrupted by a knock at the door.

"Theo, are you okay in there?" asks his dad.

He drops the card and quickly grabs the winged bear, muffling any noises it might make.
"Yeah, Dad, everything's fine!" he says... somewhat convincingly.

Cerberus bites Theo's hand.

"Ow!" he exclaims, trying to be quiet.

"Are you sure you're fine?"

"Yeah, I am! Good night!" he says, and he waits to hear his dad's footsteps before continuing.

"What was that for? I was just keeping you quiet!" he hisses at the bear, dropping him on the bed.

Cerberus immediately flops onto the ground and grabs the card.

Well. Hugs the card. It's rather larger than he is. "Okay! One down, fifty two to go!"
