The angel appeared slightly perturbed by the usage of an honorific before his name. "Just," he pointed out, all too solemnly. "Castiel. And no. Thank you."
As Selina disappeared into the kitchen, he was left by himself in the foyer with only a hatstand for company. He could see her moving about in there, catching glimpses of her distant figure whenever she sashayed into view through an open arch in the wall. Glancing clumsily at his surrounding, he was wondering whether he ought to follow her, when Isis performed a jeté off the couch and landed softly on its paws. It stared at him with its glowing eyes and emitted a childish meowl before proceeding to prowl around his legs. He watched the creature with an identical catlike curiosity as it began to rub its whiskers against his trousers in incremental vigour, marking him as its own.
Castiel's attention was removed from feline courtship by the sound of Selina`s voice. He took a step, lips parting in response, but Isis, firmly inserting itself in his way, frustrated his efforts before a word could escape his mouth. He tried glowering down at it, but this proved outstandingly ineffective. Once more, he stared mutely in the direction of the kitchen, then in the next moment, he stood directly in front of Selina, too close for human comfort, perhaps.
"That is good," he remarked. "Heaven will be grateful for your service."
