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

10. Loki Gets Captured Too

When the first trailer was released, it appeared that Loki was going to be turning up on Sakaar as a guest of the Grandmaster to bask in the entertainment of seeing his brother smushed into dust by the Hulk. But that's all now changed with the revelation that he too ends up being held captive on the planet.

Given the chains, it would appear that Loki actually goes to Sakaar looking to free his brother, and his true motives are discovered after the battle with Hulk, leading to the Grandmaster locking him up. Perhaps Loki knows how much he knows he needs Thor to take down Hela?

Regardless of the specific steps to this point, Thor obviously frees him and the pair team up to shoot their way out of the Grandmaster's venue, giving Thor the rare opportunity to play with some heavy artillery (presumably he cannot use his powers of harnessing lightning here).
