Sif & Tony
Tony checked in with his lawyers with questions well over a year ago, after talking with that current Darcy and the Valkyrie. Both confirmed what Bruce said about Loki not being the mastermind behind the Chitauri attack. That he was a puppet on a string. But since that was a sensitive subject, he let sleeping dogs lie until someone (Loki) wanted that help. So far, no word.
Tony let it drop now, although he could probably write several books about screwing up and overcompensating as a result. Sure, it might not be the exact same case, but as long as everyone in Asgard seemed ok with Loki trying to better himself, he wasn't one to judge.
"That's probably what I need. I can only code jockey that so much, before my OCD is just running in circles," he said, before catching himself. Sif probably didn't know what that was. "Obsessive compulsive disorder. Nitpicking. And thanks! I hope so too. I'm sure we'll find 'em sooner than later."
Because he was curious, he asked, "Is there anything you guys need over there? I'd like to visit sometime. See what you guys are building. Not asking for specifics obviously, but just oogling new tech is a fave pastime. Would that be okay or is it totally off limits?"
