Thor had many questions about this realm in which he had found himself, and it seemed that there were none here with the answers he sought. Those he had spoken to - with the exception of Tony Stark - seemed to be doing nothing to free themselves, some, like Clint Barton, seemed content to be here, kidnapped and in a place not of his choosing.
He, however, had responsibilities. He was king of Asgard, and his brother's punishment and imprisonment was his duty. He needed to return, for the good of his home and his people.
He had never minded helping the people of Midgard, but it was not his place to remain here indefinitely. His presence had already altered irreparably their future and their history, and had upset the balance of that realm. He would be there when their survival required it, but for him to be there constantly was dangerous.
If anyone knew - or could discover - a way for him to return to Asgard, it was Tony Stark. The man was arrogant and infuriating, to be sure, but he was brilliant beyond measure. It was with this hope that he made his way to Stark tower, Mjolnir in hand.
Letting the computer do its strange scans, he stepped inside and called in a loud voice.
"Tony Stark, I have come, and I would speak to you at once."
