[Thor opens his mouth, closes it and realises Loki is right.

Briefly, he wonders if he should keep it to himself. Keep the torment to himself but ultimately decides that sharing the burden make it easier.]

I saw visions of Asgard. It was dark, people were dancing, laughing. [He gestures, vaguely.]

There was a hooded figure, but I couldn't see his face. Then Heimdall found me, and he was drunk. I think. And his eyes were white and he said I lead us all to Hel. That we were all dead. [He's going to keep gesturing as he rambles.] And then.. all of that power. That electricity. It was coming out of me and I couldn't control it, I killed someone and Heimdall told me that I am a destroyer. [He says it pointedly. The word has been cycling his mind for some time.]

After that, I began to see infinity stones. A gauntlet. The extinction of everything and- Stark's face. Which was the worst of it.

[He gives Loki a lopsided smile.] Do you think we should be concerned.
