Każdy jest innym i nikt sobą samym.

Evidently the Demon Earth wanted to get this wedding done with so he could return home. Accepting one horse was a small price for avoiding the mischief Breanna would otherwise make. It was perhaps not remarkable that even a Demon was wary of her ire.
Breanna smiled, and the cloud over her head dissipated. "For sure. Let's get on with the nuptials."
That was all. But Putre disappeared from beside Jaylin. "He is there, invisible until you claim him," Fornax said.
"Thank you," Jaylin breathed. For the first time, she really appreciated Fornax's presence. The Demoness had delivered.
Now the wedding continued. It was beautiful. Breanna of the Black Wave, having finally grounded her man, was all chocolate sweetness and black light. The couple kissed, and all the women in the audience cried. That included Jaylin.
"Pointless sentimentality," Fornax sniffed.
"You're crying too!" Jaylin retorted.
"Not by choice." But after a pause, she added, "I wish I could marry."
So her emotion of desire had not yet faded enough. "Do Demons marry?"
"Not hitherto. But we never had emotions before. At last I understand why Demon Xanth acted as he did. He caught a case of emotion."
"I guess he did. He and Chlorine have a baby now."
"A baby. Fascinating."
"Do Demons have babies?"
"Not hitherto."
Jaylin shook her head as the ceremony concluded and folk mixed and chatted and went for refreshments. "I want more of these," Fornax said as she used Jaylin's mouth to eat a wincing misfortune cookie.
"That emotion of desire is really tearing you up, isn't it!"
"Yes. Perhaps Demon Earth's emotion of hope will linger long enough for me to share my desire and make a game of marriage and family."
A genuine lightbulb flashed over Jaylin's head. "That's why you want to borrow my body again! To approach Demon Earth in his own domain. Because you like him."
"Desire him. There is a distinction."
"Because of that lingering emotion. The Foop really got to you. So you want to follow up."
"Without being caught loose outside my own domain, and trapped," she agreed. "Your terrene body will protect me against that, and I will be able to have a safe dialogue with him. This is not a physical thing, but a site for an intellectual encounter, to negotiate terms of a special game whose actual arena of play will be elsewhere. It will not interfere with your routine at all; you need not even be conscious of my presence."
Jaylin considered. "I think I'd rather be aware, if it's all the same to you."
"It is all the same. Demons are normally indifferent to the concerns of mortals."
"But I don't think the Demon Earth has any romantic interest in you. He just wants to go home."
Fornax paused, considering. That was unusual, because the Demon minds could process worlds of information in microseconds. "He has an interest in a female, but she does not return it. This allows me a prospect."
"Well, I guess it's your business. It should be interesting."
"Interesting," the Demoness agreed with an obscure slant of mood.
Che and Cynthia Centaur approached. "Isn't this a joyful occasion!" Demoness Saturn exclaimed with Cynthia's voice. Jaylin could recognize them all, because of the effect of radiating Demon omniscience.
"A tedious pain," Demon Mars said angrily with Che's voice.
"Who would have thought it would be such an adventure?" Cynthia asked. "How little did I imagine that my simple query to the Good Magician would take me out of this galaxy."
"It was still a pain," Mars said.
"A bit of anger management," Cynthia murmured. Then she turned into Che and pressed close, giving him a double-breasted kiss. Saturn's lingering joy overwhelmed Mars's lingering anger, silencing him.
"I wonder whether we could do that, Saturn," Mars said musingly.
"Not in these bodies!" Cynthia said, jerking her bare front away from Che's.
Che and Saturn both laughed. They were rapidly catching on to the remaining mortal emotions.
"I desire that!" Fornax breathed longingly.
"I fear you can't have it," Jupiter squawked.
Fornax whirled and kissed him on the beak, silencing him too. She was making Jaylin's body do things, but at this point Jaylin didn't mind; she was too busy giggling.
The wedding celebration was winding down. The Bride and Groom disappeared, surely eager to celebrate love and hope in their fashion. In fact, they were in Castle Zombie, perhaps doing things zombies did not imagine. Jaylin bid farewell to the friends she had made, and turned inwardly to Fornax. "I'm ready to go home, before your emotion fades the rest of the way, and you depart and leave me stranded here."
"Curses! She caught on." The Demoness was still picking trace odds and ends from Jaylin's mind.
It seemed but another moment when Jaylin appeared in the Baldwins' house. Fornax was proving useful for traveling purposes, as she had the ability simply to appear at the destination.
There was David. "He's cute," Fornax remarked silently.
"Jaylin!" David cried. "You're back!"
"You noticed," Fornax said, inhaling. Jaylin was back in whole conventional clothing, but the Demoness had been quite quick to catch on how to use it to best advantage. "But this is not my back; it's my front." She angled it for best advantage, reaching a hand back to draw the shirt tight from behind.
This was becoming embarrassing. "Will you let go of me?" Jaylin demanded silently.
"Not yet. I have to deliver you all the way home." She turned slightly, shifting her knees to accentuate the profile of a hip.
"You've changed!" David said, his eyes attempting to lock onto her chest and hip simultaneously.
"Be quiet and kiss me, wonder boy."
"Please, Fornax-I'd rather kiss him myself!" But the Demoness was still busy exploring the nuances of desire.
David took her in his arms. Fornax nudged closer and gave him a deep kiss as she squeezed his thigh.
"Really changed," he said, amazed.
"That's only the beginning," Fornax said. "Now I must go home. Call me."
And they were standing at Jaylin's door in Hawaii. "Now I will leave you," Fornax said. "I have used up the last of the desire. It was fun. When David calls, tell him that he and his sister have been granted passes to Xanth, and their parents too."
"They have? How do you know?"
