Loki and The Avengers

As always, Tom Hiddleston shines as Loki, the MCU's best villain. Unfortunately, Hela doesn’t hold a candle to him. Hela asks him to kneel, just as he did when he revealed himself to the humans of Earth in the first Avengers movie.

Speaking of the Avengers, there was a moment in that movie in which Thor denied that Loki was his blood brother as he defended himself. The scene is repeated in Thor: Ragnarok, but this time, Loki says he’s adopted.

In another instance, Loki glances at the Tesseract as he’s on his way to begin Ragnarok. Given his past allegiance, we wonder whether he took the Infinity Stone before he freed Surtur.

Lastly, we should mention Loki's joy when Hulk smashes Thor like a doll in a scene that clearly mirrors the first Avengers movie’s finale, even as it begins similarly to a particular scene in Avengers: Age of Ultron.
