I like how they explained away The Infinity Gauntlet that we saw in the first Thor movie in the weapons vault as being a fake. The explanation as to what Mjolner actually represented came out of the blue, and is a rather drastic departure from the comics, but it works in that it's keeping the character from getting stale on the big screen (If you are nothing without the hammer, then you shouldn't have it!"

) And, of course, the fact that we saw a Loki's gaze lingeron the Tesseract was not a coincidence. I'm sure that hesnuck it out with him, especially with Thanos coming.*
