I saw it twice this weekend and that was really the only thing that bothered me. It seemed like an easy way out to create conflict with Black Widow/Hawkeye and have Loki create the second portal, but it really only bothered me in the smallest tinest way that I forgot about in 5 min. I was wondering, was Loki's spear powered by the tesseract, or was that the mind gem in the staff?
