I'm really enjoying this! I think this is a new variation of Fenrir!Coulson that you're handling really well and originally . Seeing Clint being overprotective over a giant wolf is definitely a new image, but you make it work (and Tony's observation about the paperwork is perfect!) It'll be interesting reading to see how everyone deals with Loki in their shared goals of breaking out his children/going after Odin in future parts :D

also this is a WIP so I'm allowed to ask you to write more, right? ;)
