Loki's grown accustomed to hearing his soulmate sing the weirdest songs, and over his time locked in his cell he's started to find them entertaining. Even funny how his soulmate would very rarely sing seriously and mostly sang horribly on purpose, he'd sometimes even hear her explode in laugher before the link cut off recognizing she was no longer singing. What happens when the Avengers request his help with a very special intruder and offer him a change of stationnent?! He's offered to help them investigate and in exchange stay there with less restrictions than in Asgard.
