This is Mumford and Sons 'The Cave' and I do not own it, obviously, as I just said that... :)

Vali and Nari have been killed and Loki has just been allowed to leave the cave where they chained him to a rock with one of his dead children's innards so this is about how Sigyn, Loki's wife and mother of Vali and Nari, and Loki felt... I also like to believe that Sigyn kind of semi adopted Loki's other children as her own because she loves Loki and they were of Loki so... why not? And also because I think Sigyn would be happy to have more children...

Also, I apologize in advance for the feels...

It's empty in the valley of your heart,
The sun, it rises slowly as you walk
Away from all the fears
And faults you've left behind.

She takes his hand as they walk slowly towards his brother and father, she watches the way his shoulders stiffen and he raises his head. She watches the change come over him as he leaves his mistakes behind, but he's only leaving them behind, he's not forgetting them. She knows he barely notices that she's there; she knows he himself is barely there but she does not mind, wherever he is, she's there with him, she knows.

The harvest left no food for you to eat
You cannibal, you meat-eater, you see
But I have seen the same
I know the shame in your defeat.

She knows that he is quick to notice none of his children are there to greet him, she knows that he knows it's because they cleansed him of his children, his mistakes. She knows how much it hurts him because they were her children too and now they are gone.

But I will hold on hope
And I won't let you choke
On the noose around your neck.

She hopes they will get through this, she hopes they can get through it but she knows she'll be there to hold his hand or to catch venom for him no matter what happens because she loves him and he used to love her too, before his heart was broken.

And I'll find strength in pain
And I'll change my ways
I'll know my name as it's called again.

He is done with them, he decides, he's done, the pain they force on him he will turn into his strength, the ways they frown upon will become his specialities, the names they insult him with will become his titles, he's done with letting them win.

Because I have other things to fill my time
You take what is yours and I'll take mine
Now let me at the truth
Which will refresh my broken mind.

He acknowledges his brother and his father as he is expected but the moment they return to Asgard, he and Sigyn go off on their own with Sleipnir, they have more important things to do. They World Walk back to earth and go swimming with Jormungand; they call Hela from her halls and go picnicking on the boughs of Yggdrasil and they visit Fenris and talk with him for hours. They are his true family, they are the only things that should matter, forget the court, forget the king, forget the crown; they never cared for him.

So tie me to a post and block my ears
I can see widows and orphans through my tears
I know my call despite my faults
And despite my growing fears.

He thanks them for chaining him in that cave, he thanks them for placing a venomous snake above him, he thanks them because it only served to show him who really mattered to him. He thanks them for showing him who he is, a father. Despite all the things he has done wrong, he is still a father, and it doesn't matter that they took and killed his children; it doesn't matter because he is still a father and he knows that. It scares him to think about what's in store for his little family later on, it scares him because haven't they suffered enough? It scares him but he will still care for them and he will still love him and he will defend them no matter what because he is their father and that's all that matters.

So come out of your cave walking on your hands
And see the world hanging upside down
You can understand dependence
When you know the makers land.

She doesn't know if the change in him is good or if it's bad but it doesn't really matter because she knows neither of them will ever be the same after what happened. It scares her but she knows him and she knows where he's going and he needs her so she will be with him, every step of the way because they are tied together by the sorrow they share.

So make your sirens call
And sing all you want
I will not hear what you have to say.

He does not speak to his Royal Family for months, he acknowledges them when he remembers and oft times not even then, he cannot bring himself to do it. His brother gives him puppy dog eyes and tries to plead with him but all it does is remind him of how they would not listen to his pleas as they turned one son into a wolf to kill the other. Frigga cries and always calls his name when she sees him but he ignores her because all it does is remind him of Sigyn crying and wailing his name and their sons names as they tore them from her arms and held her down as they killed them. He makes it his purpose to avoid Odin at all costs and he succeeds.

And I will hold on hope
And I won't let you choke
On the noose around your neck.

It's raining when he kisses her goodbye, they're outside a little hut in a forest down on earth and he's had to beg and plead and cry and bribe and trick and compromise with her to get her here. This little hut is now her home and she agreed to stay there only if he would visit her at the end of every week without fail unless he had given word he would not be coming. It had taken months to get her to agree and he'd been so relieved and so exhausted when she had. He knows she understands why he's doing this but he knows that she wants to be with him too, and he wants to be with her but he can't bear the thought of them taking her away or hurting her because of him, he just can't stand it, so this is how it has to be. There is nothing holding her to Asgard but her loyalty to the king, and it still threatens to strangle her, even here but he won't let that happen.

And I'll find strength in pain
And I'll change my ways
I'll know my name as it's called again.

She learns to be strong, learns to take the pain in her heart and turn it into strength, she learns not to love so easily and so deeply and she learns how to survive. She befriends the woodland creatures so she doesn't get lonely and she guides travellers through the forest when they get lost but she never gives her name when they ask but she still knows it and she's just waiting for it to be called. She's just waiting for the time when she needs to be 'mother' or 'wife' again because she knows that's all that really matters, her husband and the children they love. She learnt the hard way that family isn't synonymous with 'love' and it's a mistake she will never make again.
