Author's Note: I don't know why I wrote this. I hated the end of Game of Thrones and what it did to Daenerys, and I don't think the books will go that way.
But I guess Jon killing Daenerys made me think of the ending of Days a bit, so this sprang to life. Though I did try to make it somewhat better than Game of Thrones' ending.
Sorry for this, guys.
Tragedy. Major character death.
Collateral Damage
Was Roxas partly afraid that Xion's dragon, Pluto, would kill him for what he was about to do? Yes. Did he care about that even remotely, with the knowledge of what he had to do to the girl he loved? No.
Xion was now pacing about in King's Landing's destroyed throne room (of course she was, a bitter part of Roxas thought). And she had such a look of wonderment on her face, as she took it all in. It was the look Roxas had fallen in love with. And it was so hard to believe that this sweet, innocent girl had just killed thousands of people for no good reason. And yet, here they were. And yet, Xion didn't even seem to realize she'd done it.
Which was why Roxas had to step up.
"Xion, do you even realize what you've done?" Roxas demanded. And he would have liked to believe that more than anything, he was pleading with this and asking Xion to atone. But he worried that more than anything that when he spoke, he was more horrified that Xion could wear such an elegant lavender dress amidst this carnage,
"...I just defeated people who would have become White Walkers. Roxas, you know all the ones we fought in Winterfell couldn't have been the end of them! Looking back on it, I think some had broken off and were heading for here!"
To be honest, Roxas felt the same way: that the others couldn't have possibly been defeated that easily, and that they would all be back someday. But he didn't think it would happen yet! And it didn't at all give Xion an excuse for what she'd done!
"Xion... Just tell me you're sorry. For any of this. If you do, everything will be okay!" Roxas exclaimed, holding steel in his hands as he shook. He thought that Xion saw the sword—he hoped that she did, because he didn't want to do this by sneaking up on her—and that deep down, she wanted to be destroyed (and this had Roxas worrying his lip so much, that it bled.
"No, Roxas. I can't!" And if nothing else, Xion's face was entirely tragic as she said this. She looked like she was fighting back tears… but why did she fight them? Roxas wondered, taking a step closer to his girl. ?Not when any of those people could have become White Walkers, making the eventual casualties worse! ...And now that I think about it… I could turn into one myself now, for having been touched by the Night King! So, please, Roxas. Kill me."
And Roxas did, sobbing as he did so and cursing what a cruel place Westeros was. But he stood in front of Xion as he drove the blade home—stabbing the broadsword first through himself and then her, so they might die together.
As the two of them fell to the ground together, searching for each other's hands, their souls soon began flying towards the sky—where a better future hopefully awaited them.
