After Loki's attack on Manhattan, he is sent back to Asgard and is sentenced to imprisonment. Except the second Thor leaves and returns to earth by choice, Odin transfers Loki to the dungeons and brutally tortures him until there is nothing left of the Loki that everyone knew, and becomes terrified and overly submissive, hiding his scars and never opening his mouth to speak. When Thor returns seven months later, he sees this but is not told why his brother has become like such. In a panic, Thor decides to dump him with S.H.E.I.L.D and is kept under watch by the Avengers in order to get him away from Asgard. To everyone's shock, he is too busy being terrified of punishment to try anything. Tony's suspicions get the best of him and when he ends up trying to 'rehabilitate' Loki, he get's far more than he bargained for. --this is a reprint from my a03, so I will not be making any gramatical fixes on earlier chapters-- 2019 update: AH SHIT ITS AT NUMBER 1 IN FROSTIRON TAG HI EVERYONE! I swear I'm still working on this, please don't crucify me!!

Tony runs into Loki with his car and things get out of hand for him
