Abby had mostly shed the feminine form, and Sylan had yet to truly adopt a human one. For the sake of brevity, Sylan shall be 'it', though it is more animate than that implies, and Abby shall be 'she'.
Sylan was smiling, or doing something we would best understand as a smile. "Ah, the lovely lady Abigail. Delighted." Sylan bowed over Abby's hand.
Abby sighed and muttered, "Again?"
Sylan straightened and tipped his head to the side. " 'Again'?"
"At the very least I can imagine an excuse for Margaret."
Sylan grinned at the confirmation of his guess. "You can't destroy something that encompasses you, darling."
Abby let out a huff, then realized she suddenly looked like someone's (overdone) idea of an adolescent daughter, make-up and all.
Mostly due to Maggie's influence, she deadpanned, "You're not even my real Dad."
Sylan laughed. "Oh, I can see why Maggie liked you. Where did she get off to, anyway?"
"Here," Maggie said, fading in draped over Abby's shoulders. "I die sometimes, though. It's vaguely unpleasant."
Abby gave the long-suffering sigh of old souls and the pretentious. "If you did not insist on touching me..."
"Aw, now what fun is that?" Maggie kissed Abby's cheek. "Wouldn't ever get to do anything, if I went around doing things like that." She glanced at Sylan. "You alright with this? It looks like she's thinking of herself as your child."
Sylan shrugged. "She isn't." It suddenly looked curious, itching to figure something out. "Any pattern to when you die?"
Maggie's eyes danced. "Midnight."
"And does it happen if you're not touching her at midnight?"
"No." But there was laughter in her eyes, and Abby had the barest hint of a smile on her lips. The not-quite-smiling woman breathed, "Three, two..."
"Then why not just refrain for a few moments?"
Maggie laughed outright. "My midnight, dear. Don't you know the stories? Midnight can last hours."
"Days," Abby added, eyes crinkling.
Sylan blinked. "That makes no sense."
"Magic," the girls said together. Maggie continued, "I'm not of your realm, Sy. Good on you for trying though; it'll work anywhere but here." Magic lifted one hand to gesture to the not-space that they had quasi-manifested in. "Wouldn't've, but then Abby convinced me to stick with her." Mag's nose buried itself in the hair behind Abby's neck.
"Some would believe it good for them," Abby said, dancing around a direct statement. " 'They can figure it out now.'"
"I could've given them the exact measurements on the first try, if I wanted to," Maggie sighed in the tone of an old argument.
Sylan shook his head. "Do you follow any rules?"
"I can't create," Abby said, at the same time Maggie said, "I can't destroy."
Sylan blinked. "You two together..."
"Would be a force to be reckoned with," Maggie said cheerfully. "Good thing I've decided not to do anything to the world anymore, or we'd probably be running the joint as non-benevolent dictators. It's just so hard to keep track of who's a person, you know?"
Sylan half-smiled. "I just try to be fair to everything."
Maggie shrugged, then began fading. "Oh. Midnight. Going to take a few minutes this time, I think."
"I'll leave you two your minutes, then. See you later."
"Eventually," Abby noted.
"Probably not me," Maggie said in a chipper tone. "I only come out when it's dramatically appropriate, and you've already met me once."
"What about Abby?"
The Cheshire Cat would envy Maggie's grin. "Well, I hardly need to follow all the rules."
