You've got a friend in me

After faking his death in the Dark World Loki is free to do what he wants. Instead of leaving everything behind Loki is driven by his thirst for revenge and won't find peace before he destroyed every single one of the Avengers. This time though he won't use violence, but the weapons of the God of Mischief: trickery, deceit and illusion. Loki decides to befriend the Avengers. However they won't know it's him. Not until he is close enough to strike. Unfortunately Loki didn't consider the possibility that he might get too close.
