The talk of the content of the SDCC footage also has me pumped. I never even considered something like "hand gate" or the like. If we get a quick glimpse of Kurse and some of his throwdown with The Thunder God as well as a snippet of Loki interacting with Jane and Jane and Sif I will be happy as a clam at high tide.
Do you think Jane will get to explore for the audience the fact that these beings were at some point in Earth's history worshipped as gods? As a scientist it wouldn't be out of character to be curious about that.
