He is currently flying through space between worlds. He doesn't have a destination in mind, and he doesn't plan to stop running because he is afraid that Loki will be able to find him.
To him, the possibility that Loki is currently pursuing him and can find him is high because Loki's final attack is still bothering him. Apparently, that yellow glow on Loki's fist hadn't been simple after all.
Right now, his entire body is glowing a dim yellow light. This is not his natural state at all, and he is not the one making the yellow light.
His natural state is to have a silvery gray complexion. But now, he is yellow like a mortal with jaundice and liver failure.
He doesn't have a liver, but it is clear that he is sick. And it is all because of Loki.
At least, he doesn't doubt that Loki is to be blamed for this. He is so sure that Loki is responsible for his current plight that he is willing to stake his life on it.
