We knew it might well be coming in Secret Avengers #27. Because of, you know, the cover and content descriptions, and that kind of thing.
But instead, it turns out it actually happened in Secret Avengers #26. In deep space, the body of Mar-Vell is captured by the Kree race, who then use the M’Krann crystal to divert the Phoenix on its way to Earth, if only momentarily.
And why? So that they can all sacrifice themselves and see their precious Captain Marvel revived. So that he can turn up for an ominous chat with Ms Marvel – about to be the new Captain Marvel. And Marvel Boy, sometimes referred to as Captain Marvel.
Just as DC Comics have abandoned the Captain Marvel and Marvel Family names, looks like Marvel are making their own. Even if they’ll all end up having the same name.
