It's been two months since Loki's official integration to SHIELD as a consultant, and someone jokingly writes on the general announcements board:
S.H.I.E.L.D. PRIORITY PROTOCOL FOR EMERGENCIES INVOLVING IMPOSSIBLE INCIDENTS:
1. Blame Loki
No one disagrees and it becomes another of SHIELD's unofficial rules.
Or, Loki is taken in by SHIELD after his fall from the Bifrost lands him on Earth, and he proceeds to show everyone, constantly, why he deserves the title ‘God of Mischief’. Fury is not amused. Neither is everybody else at SHIELD, except maybe Barton.
Mostly, all of his beginnings were different. Time varied and places seldom repeated. Even the nature of his own magic was unpredictable. Yet, every single time, there was something he could always rely on, a beating heart, even if its shape was never entirely the same.
And that would have been enough, except it wasn't.
