Stephen pondered over which ways to prove his worth to a warrior of Asgard. Showing her the mirror dimension might be thought of as a threat or a trap, so that was out of the question. She probably wouldn't want to step through a portal, even if he promised to take her to Thor. Options were limited. It was all down to talking and for someone as socially awkward as Stephen had gotten lately, so set on learning all he could as fast as possible, that was going to be a hell of a task.
He opted for honesty being the best policy.
"There's a lot I could do, to show you what I could do. But I don't want you to think it's a trap or an attack. I can tell you that Thor first came here with Loki. I had a talk with him about his...family issues. He left. Now they're both here again, along with a valkyrie. I can show you how to text Thor using a small device, if you want. I could portal you to a meeting place. Or we could get a taxi. That works too."
Stephen thought it was better that the news of Asgard's fall came from someone she knew.
