It gets so much easier to write Sigyn where you see a Darcy without her glasses and dressed in Asgardian robes standing there.
Although Loki was happy to walk out of the arch with Percy, he made sure to warn his new-found grandchild to be discreet about mentioning their relation to each other before taking his leave. He also made certain to leave a clone of himself transformed into a sparrow watching Percy and his friends while cloaked in seidr to be doubly certain he could watch them without being discovered. After all, it would not be to anyone's benefit to notice Loki watching the trio too closely.
He also needed to teleport himself back to Asgard to gather his thoughts. the very notion of having a grandchild after all this time was a heady one for him indeed.
Loki appeared in his chambers in the Royal Palace in a gout of green flame as he tended to do when not cloaking himself and noted that Sigyn was there waiting for him. She was reading again, this time some popular magazines from Midgard. From what Loki was told the Allfather had a special project for her in the next couple of years that was to be kept quiet and she needed to study up on Midgard as part of it.
Sigyn looked up at her husband with concern as she asked, "Loki, you look worried. What is it?"
"Whatever do you mean?" Loki asked with feigned innocence. "I am perfectly fine."
Sigyn's face took on a sarcasticly knowing expression that most of Asgard would believe her incapable of as she replied, "I think I know you well enough to know when you're troubled, husband. You can't hide anything from me. Now what has you looking so upset?"
Loki met her gaze for all of a minute before sighing loudly to himself and giving a tired chuckle as he asked, "Whatever happened to the quiet and blushing maiden I first courted that all of Asgard believes incapable of having an ill thought toward anyone?"
"You learned she just kept her mouth shut to keep from dealing with idiots like Theoric and that she had a brain in her head that actually attracted you far more than her generous chest did," Sigyn noted without wavering in her expression.
"True enough. I think Thor and his little band would go to pieces if they knew you even half as well as I do, my dear wife," Loki acknowledged with a smile.
"Hogun would be fine. And Sif would probably accuse you of doing something to corrupt me," Darcy noted with a wry grin.
"But nothing that you do not thoroughly enjoy at every opportunity," Loki responded lasciviously.
Sigyn shook her head as she noted, "And now you are trying to use sex to distract me instead of just telling me what is bothering you. This must be big to have you so concerned. Should I be getting ready to greet the guards before the Allfather has you imprisoned for a few years?"
Loki seemed to slump in his seat and she shoo his head and replied, "It is not anything I did this time. I discovered something that will have most of the Realm Eternal up in arms soon, though."
"What could that be? I thought you were tracking down the source of that odd prayer you sensed?" Sigyn asked.
"It seems I have more family, blood family at that, than I knew about. It was my... grandson that sent the prayer," Loki explained.
"Grandson? But how could you possibly...? No. You mean to say Hela of all goddesses?" Sigyn asked as he eyes lit in realization.
"Indeed," Loki confirmed tiredly.
"But how? I mean she is confined to Nifelheim," Sigyn insisted.
"I... may have taught her to create a duplicate shade of herself. And how to walk the old paths without a Bifrost. And... perhaps how to avoid Heimdall's eyes. Just as birthday presents, mind you," Loki explained with a mischievous grin, thoroughly proud of what he had done.
Sigyn tried to remain stern for a few moments before breaking down into a kind grin as she moved in and kissed her husband on the cheek. "You are a good and loving father, Loki. I'm glad you could give her at least some degree of freedom. So I assume the child she mothered is some kind of demigod?"
"Well, that's what he believes at the moment," Loki noted with a grimace.
"Why do I get the feeling this is going to give me a headache if I ask?" Sigyn queried.
"Because you have lived with me far too long," Loki replied knowingly.
"And I would not trade a moment of it for anything. Now what did you mean when you said our new grandson thought he was a demigod?" Sigyn asked.
"Our grandson?" Loki asked with a raised brow.
"Just because I did not give birth to Hela does not make me any less her stepmother. I am still you wife and your grandchildren become mine as well. Now tell me about my grandson before I decide to pop down to Midgard myself and ask HIM what all the fuss is about," Sigyn commanded.
Loki sighed and shook his head ruefully before he said, "Apparently my little girls likes to aim high in terms of consorts. Her shade apparently caught the eye of Poseidon himself and young Perseus was the result. Not that the child had any idea. Apparently she told his her line was descended from me without telling just how closely the family lines really are."
"Lying without really lying. She does take after you, doesn't she?" Sigyn asked with a smile.
"Quite. She used it as an excuse to explain her seidr which she taught him while pretending to be mortal. He only learned about Poseidon being his father within the last month," Loki noted. "Apparently she was accused to stealing that oaf Zeus' Master Bolt and his mother was somehow captured by Hades in the conflict. He is on the way to the Underworld to presumably retrieve his mother and the bolt together."
Sigyn looked pensive as she noted, "That sounds a bit dangerous. How old is he?"
"He's twelve by the local reckoning..." Loki began.
"TWELVE?! And you LET him go? Are you insane? He's just a child!" Sigyn exclaimed.
"It was a formal quest from the Olympians. I already dispatched the monsters bothering him at the moment and I have a shade of my own watching him and his little friends. He will be safe enough until he enters the Underworld," Loki assured her as he raised his hands in a calming gesture.
"And what about when he gets there?" Sigyn demanded, fully aware that Loki could not enter another divine Realm like that without permission.
"Hela will watch out for him, then, I am certain. Much like me she can fully manifest herself wherever one of her shades is present. Should Percy's paternal Uncle get too bothersome he will have her to contend with and she is easily a match for Hades," Loki promised.
Sigyn stared at her husband for a full minute before she noted, "You had a shade hiding ON our grandson in the form of a bug or something, don't you?"
Loki laughed as he cupped Sigyn's chin and kissed her gently before he replied, "As I said, my love, you know me too well."
"He will sense you Loki, and he will blame the boy," Sigyn warned.
"I find your lack of faith in my abilities insulting," Lokie replied with an affronted air.
"This had better not blow up in your face, husband. I will be very cross with you if my new grandchild is harmed before I have a chance to spoil him," Sigyn warned.
"I can assure you I would bring ruin and destruction to all of Olympus and the Underworld before I allowed that to happen. But I can't very well interfere in the boy's quest unless there is no choice. How could I deny him his adventure when I was doing the same with Thor at his age?" Loki asked.
"Fair enough. I suppose you will be looking for an audience with Hela in the meantime, then?" Sigyn asked.
Loki nodded once in agreement with her question.
"Tell her I would like the chance to meet me grandson. I will not have much time before I am busy with the task the Allfather asks of me but I still want to know my first grandchild," Sigyn informed him.
"I shall relay the message to her. Once we are done discussing her penchant for hiding important information from her father, of course," Loki promised with a hard look in his eye. Oh yes, he and Hela were going to have quite the conversation very soon.
