He had not truly expected to ever awake again.
When his eye had closed for the last time, when he had floated free of gravity or further concern, Thor had only the ember of his word burning within, the promise he'd made to a tyrant who had stole everything left of worth from him.
His oath was inviolate, of course, even in these straights. And he held what strength he had left within him in reserve. Even this exposure could not kill him, but the void was vast and the likelihood of rescue vanishingly small.
Yet the Norns work in mysterious ways. Particularly where his people — what remained of them — were involved.
Redemption had arrived at the hands of some unlikely souls, but Thor was in no condition to turn aside aid. Particularly when the body of his brother had arrived not long after he himself, impacting their ship and prompting some excitement amongst the Rabbit's crew.
Grief welled thick within him, then, from a place in his heart he had thought so wounded it could no longer ache so fiercely. Thor had asked for a few moments of privacy, hoping to make what peace he could with his brother before he began his quest of vengeance in earnest.
Expecting Loki to fall had perhaps been his biggest mistake. Believing that he could, after being deceived so many times. That loss was what he had always feared most, even when they were at odds, and Thanos had claimed the mantle of the soul killer. Even though he knew Loki, he had, in that moment, believed.
"Loki." A storm of confusion, shock, anger, and overpowering exaltation swelled within, lighting the room around them as he braced his hands on his brother's arms and drew him in. He lived.
"Take care, brother. One day, I will not endure your trickery. We have lost enough, and I have no desire to survive you."
