Thor laughed again, finally releasing his brother and giving him a playful shove, "It isn't as though I've had much time to change," He said. "I have only just arrived. Besides, this armor has no pockets, and the item I was given is very uncomfortable jammed under my breastplate," He said, shifting awkwardly as if to illustrate the fact. Glancing left and right from the library, Thor furrowed his brow, though, he suddenly realized that he had absolutely no idea where to go from here. The library was the starting point, and he'd gotten a handful of details. But there wasn't really anything useful as far as day to day operations went.
"Of course, in order to do that, I would need something to change in to," Thor said, turning his attention to his brother with an expectant gaze. Because, yes, this was the name of the game when they were just Thor and Loki. Thor gets them into a situation, and Loki gets them out. It was a formula that he worked magically for years. Why mess with a classic?
