These issues are a mishmash trying to make sense of the fact that Jane Foster and Sif have merged bodies, which led to Don Blake and then another doctor being accused of murdering Foster (since her body has disappeared, she is missing), and then led to some kind of involvement with a vaguely Egyptian mystical entity. It’s really bad.
I can’t read it close enough to make sense of it, but the gist is that in the end Sif and Foster are split again.
