Thor: Ragnarok - 10 Huge Spoilers From The Comic Con Trailer

2. Thor And Bruce Escape Sakaar Together

When the first trailer landed, it looked suspiciously like Hulk had lost himself and would be fighting Thor for real in the Sakaar arena and that Thor subsequently escapes the planet with Valkyrie alone.

The new trailer changes all of that: the arena fight ends with both still alive (though Banner being around suggests Thor might actually win by declawing Hulk), and a couple of shots show the pair in a spaceship escaping the planet (presumably through the giant portals above the planet's surface).

Presumably the same ship also ferries Valkyrie and Loki away from the planet, with Valkyrie no doubt turning on Grandmaster when she realises that Hela has risen once more.
