When Loki arrives at Avengers Tower declaring he’s given up his super villain ways and wants to be a hero and an Avenger, Thor, Black Widow, Captain America and the rest of the team are skeptical.

It’s a brilliant plan… until Thanos arrives and the Avengers discover Loki’s sudden good intensions, like Loki himself, may not be all that they seem.
