The Mysterious Woman of Asgard

One day, as Loki paces back and forth in his cell, he is visited by a woman known to Asgardians as "The Mysterious Woman of Asgard" and is very much feared. Yet she has never done anything wrong. She believes she can help Loki & bring out the good in him. But will their friendship become something more? BTW, This happens after The Avengers, but before Thor: The Dark Worlds.
