Tony groaned as his phone woke him up, Tony wasn't one to ever sleep that well, so being called in the middle of the night didn't make him very happy. "Coming... since I am not allowed to sleep." he snapped .
He knew he was going to just be cranky. He never got on well with Fury anyway.

He gets up and gets ready to leave and flies off in his ironman suit. Reindeer games really did have to pick an annoying time to come. He looked around and saw the other Avengers and SHIELD and a passed out Loki.
It was the first time Loki hadn't even budged.
