when you realize that Frigga was one of the last ,if only, person that Loki actually cared for. Her death broke his heart partially because he blames himself for it. There's no going back for Loki Tom did an amazing job capturing that on screen.
Avengers: Shawarma and Loki - it's funny cuz every time i watch this movie, i always wonder where Loki is during the shawarma scene. And to make this even sadder, Thor is having the time of his life while his little brother is tied up.
