Really, all Tony wanted to do was test his newest baby, the Interdimensional Portal he and Jane had build after the Chitauri attack. And sure, Jotunheimr might not be the best place for a test drive, but - hey, ice as far as the eyes reached, natives whose most advanced tool was the axe they carried around with them, so what should go wrong?Well, maybe someone should have pointed out that the jotnar hid some of the most advanced labs in the whole universe under those snowy mountains. And that their king would rather keep the accidental traveller as a servant in his palace than let him spread the word.
