Thor pulled the covers up and dropped a hand on Loki's arm one last time. He would have given it a light squeeze, but his his hands still seemed to feel the phantom trace of Loki struggling against them and he couldn't make his fingers close again, even gently.

"Sleep, brother."

He didn't think that Loki heard him, but it hardly mattered if he did. He was no longer in pain. That was what mattered.

Without Loki leaning on him for support, Thor sank to the ground beside his bed, leaning back against it so he could hear his brother's still uneven breathing behind him. He tilted his head back and closed his eyes, but it did not stop the tears leaking from them. His strength seemed to desert him. There was so much shame in this already, he could not be bothered to posture at pride in front of Sif, who already knew him too well.
