ComicBookResources has the preview of #646. KidLoki's tale is ended, Sif's tale is about to begin. If the Kathryn Immonen and Valerio Schiti are playing a long game like Kieron did before
them, I am looking for clues and cues right now.
(Don't like being stung like that)

I have to say, I know it's just a few pages, but for some reason it's like reading DCnU Diana of Themyscira... I hope we get a lot of development to really make Lady Sif stand out on her own (aside from Red She-Hulk and Brunhilde the Valkyrie right now).
Still stings right now to play in Asgard, but if ever there was a happy home that would soothe the wounded heart, it's the home of Lion of Asgard, Volstagg.
