Case in point, the Infinity War trailer showed what looked like Asgardian bodies strewn about right before Loki was seen holding up the Tesseract.
Aside from Thor clearly being in pain and a ridiculous amount of energy erupting behind him, it’s unclear exactly what’s happening here.
However, we have to remember that in the trailer, we only see Thor in space, whether it’s this strange location or aboard a spaceship.
Let’s also not forget that in Thor: Ragnarok’s mid-credits scene, the ship carrying Thor, Loki, Korg, Valkyrie and Asgard’s citizens was intercepted by Thanos’ much larger vessel, and we know nothing good will come from that.
