Pouting just a bit, and keeping her hand where it was just in case, she twisted her body around to face him, "Oh, alright... I suppose we can part as friends. I'll even get your shield down for you, okay?"
Taking what little advantage of the situation she could continue to muster, Cat planted her lips against his while regretfully letting go of the national treasure. It was brief lip lock that couldn't really be called a kiss and had her smacking her lips together after pulling away from him. One arm snapped out and the grappling hook zipped off to wrap around the ceiling beam his shield hung from. She yanked on it to send herself flying upward about ten feet before climbing the rest of the way.
Manually winding the cable back took another minute and then she was walking casually over to the belt, like a gymnast on a balance beam. Completely comfortable despite the narrow path and the height at witch it sat. The belt snapped with a swipe of her claws and she caught the metal disk before it could fall.
Cat tossed the shield to him frisbe style and with a grin, called down in a purr, "Avengers Assemble."
