Thanks to Enberlight for the quick once over. :3

I've been...inspired by the spoilers. Probably not going to re-write the first chapter, though. ;)

Chat Noir looked at her expectantly as the Mouse Kwami slipped free of the necklace. Marinette, this is Mullo. He's a Kwami, a being that will grant you powers like mine."

The tiny mouse Kwami beamed. "To activate your powers, you'll need to say 'Whiskers up.'"

"Do you have a little time now?" Chat bounced on his heels eagerly. "I'd kind of like to take you out!"

Wide-eyed, Marinette blanched. "W-what?"

Chat Noir warmed to the tips of his very human ears as the implications of his hasty words sunk in. "Oh! Sorry! I meant...on patrol" One claw slipped behind his head, anxiously raking the hair at the nape of his neck. "It would be good to take your powers out for a test run. To give you a little time to get used to everything."

A pretty, soft blush burned Marinette's cheeks. "Well...I didn't really eat much for dinner." She frowned, not quite meeting his eyes, even when she'd peered over in his direction. "Is this going to tire me out? Or do you think I should I run down and grab something really quick?"

Smiling softly, Chat Noir leaned back against the balcony rail. "I don't usually need anything, but I suppose it couldn't hurt."

Exhaling, Marinette's shoulders relaxed a little. "Umm...Mullo, right?"

"Right."

"Do you need anything to eat, too?"

"I would never turn away a bit of cheese." Mullo's lips curved up in a secret smile. "And I know Chat Noir's Kwami wouldn't either."

"Great!" Marinette squeaked, stumbling slightly as she rushed over to head downstairs.

Chat's clawed hand reached out to help her without hesitation, speeding across the few feet, but Marinette had caught and righted herself a bit more deftly than he'd expected.

Her breathless smile was a little shakier than her legs, as she turned back to reassure him. "I'll be right back!"

He couldn't help but feel the infectious smile slip onto his own face as he watched her descend down into the darkness.

Marinette had been the first one on his mind. She was clever enough - and quick - but easily underestimated. When he'd asked Master Fu for advice, his mentor had just peered at him for a moment, deep in thought before pointing him towards the Mouse Kwami.

Chat Noir glanced over at Mullo, who smiled quietly out into the starry night. "What do you think?"

Mullo glanced back at him warily. "I think...I couldn't have asked for anyone better for a holder."

Chat blinked at that. "But you haven't both transformed together yet. How can you be so sure?"

Mullo simply chuckled. "Call it a sixth sense about these things."
