Loki Episode 3: 10 Biggest Questions
5. Who Hurt Loki?
Love is a dagger, beautiful to look at until it makes you bleed, and when you reach out to it, you find that it isn't real. It was an admittedly clumsy metaphor, but this was Loki's description of love, and no one describes love like this unless they have been hurt.
Loki's romantic life is something that has never been explored in the MCU before, but as Sylvie suggested, there must have been someone in the Asgardian Prince's life. The titular character confirmed that he is bisexual in episode three, and that there have been love interests in his life, but nothing has ever worked out for him.
While Loki and Sylvie's conversation did lean towards love in the romantic sense, Loki's answer may have revolved around his family. He loved his father, until the reveal that he had been adopted and lied to all of his life. He loved his mother, but just days before had to watch her die at the TVA, but the love that hurt him the most was that which he held for his brother.
Even though he hated living in Thor's shadow, he loved and respected him and only wanted to be his equal. Though he didn't experience it himself, Loki has just learned that he sacrificed his own life to save his brother's on another timeline. This could be what he is referencing by love making him bleed, or alternatively it could be some previous romantic love that is yet to be explored on screen.
