Maryanne padded over to him, unable to resist the urge to nuzzle her large feline head against him. Her barrel chested purr rumbling to life the moment she had set eyes on Bucky. Not noticing Clint in the bed just yet. It was hard to off hand, in his room, as Clint's scent seemed to permeate in the room, almost as much as Bucky's did.
Her eyes teared up just a little when she noticed what shirt he held. The feel of it against her nose alone was enough to tell her it was the one he wore rather often. She raised up on her paws just enough to press that semi wet nose against his cheek. She had to do her best not to cry as her human self, so anything close would have to be gotten out while she was still feline.
The purr rumbled a bit louder as she licked over Bucky's hair, just once. He might not be hers in flesh and blood, but he was in her heart. And she'd missed him to the point that it physically hurt.
