Lights Out
Post-Avengers.
Brought in chains back to Asgard, Loki has a choice - marry Thor or die. He chooses life... for a moment.
“And to think they call me the monster. What are you, really, Thor? How deep does this perversion of yours run? How did you hide it so well? You are not as golden now, are you, Odinson? Never have been. I am quite peeved that I missed this. Imagine the Hel I could have turned your life into if you had revealed yourself sooner.”
