"The power of a sentinel mother is a great one, Detective," Puck snickered, his grinning face irritating the irate, but pleasantly sore Elisa Maza.

"How do you mean?" Xanatos asked, brown eyebrow raised curiosity, voice still slightly slurred with sleep.

"I mean, my dear David, is that sentinel mothers are designed for breeding and child rearing and can jump start breeding whenever they choose, regardless of species. Sex just makes them start the heating cycle automatically. It starts because of pheromones realize and how far that realize can go, and yes, magic can spread it rather easily if magic was as involved in it last night. To which it wasn't, at least not enough to spread the pheromones to a wide degree, just enough to affect the castle inhabitants," Puck replied, head tilting.

"Did you two have sex?" Fox asked, green eyes widening and a smirk coming to her lips.

"Yes," Puck let out a gleeful laugh, grinning broadly.

"What?" Elisa snapped, worry filling her.

"He's eighteen, Detective, a legal adult by American standards," Puck replied calmly. Elisa fumed slightly, her lower lip pouted out in a rather childish manner.

"How do you know so much of sentinel mothers Puck?" Xanatos asked, always the curious one, always wanting more. Puck frowned slightly, wondering slightly if he should worry.

"I'm over a thousand years old David, Roe isn't the first sentinel mother I've ever met, nor the last. He's just the only one I've ever been interested in. Sentinel mothers usually gently nudge the heating cycle, but when sexual acts happen, it bursts it forth rather aggressively. His pheromones will also induce ovulation in females, regardless the species and regardless if a human female already had a menstrual cycle." Puck explained, unconsciously moving closer to Roe. Both human females eyes widened in surprise and shifted nervously. Then Elisa crossed her arms with a snort, a frown marring her full mouth.

"Your aware that your mates now right?" She snapped, her over protective 'big sister' instincts on over drive. Roe, Angela, Fox and even Demona were the closest female friends that she'd ever had, and Elisa was rather protective of all of them.

"I know Detective, trust me," Puck replied, his hand never stopping with the gentle petting to Roe's stone hair. Elsa nodded and stretched her back until it popped rather loudly. Fox made a disgusted noise and Elisa sniggered at her. After two months of arguing, Goliath had finally gotten Elisa to move into the castle, so she would be safer from groups like H.A.M. She was sure thankful for it now, considering that she not only got to be around him all the time, she didn't have to drive to her apartment at the moment with how sore she was at the moment.

"You really like Roe, don't you brother?" Fox asked, red head tilting. Puck stuck his tongue out at her and Fox smiled.

"Yes, I rather do," Puck replied, dissatisfied with the 'brother' comment that Fox teased him with. Titania had ended up telling Fox that Puck, like the other avalonian children, were considered both hers and Oberon's 'children'. Thus, Fox relentlessly teasing him with the word 'brother' at every chance she got. The ginger haired women seemed determined to keep calling him it, so Puck relented in letter her call him that. Both Xanatos's had a feeling that was do to Alex, and the little boy calling him 'uncle Puck/Owen' every chance he had since he learned to talk.

"Are you going to marry him?" Elisa asked, rather tiredly, cracking her neck in the process.

"If he gets pregnant, yes," Puck replied nonchalantly. The humans frowned in distaste.

"What do you mean, 'if he gets pregnant?' That's the shittest thing a guy could ever do." Elisa snapped angrily.

"Eli's right, that is pretty low," Fox replied, her own green eyes going cold.

"I thought I knew you better than that Puck," Xanatos said, frown marring his face as he crossed his arms.

"Breeding is nearly impossible for us Fey. More times out of not, we have to sleep around to see who we're able to breed with. If a female gets pregnant it's a big thing, her and the father will, more or less, be forced to marry. This is all done regardless of loving or liking the other half of the party," Puck replied, a hint of annoyance finally seeping into his voice. His delicate hands were clutching angrily at the humans lack of knowledge. The three looked at him surprised, the information circulating through their heads in a dizzying dance of saddening information.
