Chapter 8.

Surprise! Well, not actually surprise, given the usual dramatic cue of Bella never having found his jewelry in the ashes. Presumably, the vampire they burned there was Irina, who would have caused problems for the Volturi if they seemed to be in the way of not killing the wolves.

So in the future: Edward still has the mate bond to Bella, presumably, because it's stated somewhere (I think) that Chelsea is not powerful enough to harm that. Is Chelsea+Chelsea!Del enough? I somehow doubt it. In that case, if Edward can see Bella, then they will immediately align. So in the long term we probably don't have to worry about the psychologically-traumatised-Edward storyline, or at least he's unlikely to be killing people of it.

How does Chelsea's power work? It is stated that she killed all the relationships that the captive witches had with others; how does this affect their memories? Will Edward realise that Elspeth is his daughter? Will he if she tells him so, or shows him? Will his attachment to Bella spill over onto Elspeth and overcome the indifference-bomb? In any case, it seems to me that the best thing for Elspeth to do right now is (assuming she can get close enough) to immediately show Edward the highlights of Bella and Elspeth's life while he was captive, roughly: "Bella is alive", "I am your daughter", and "Bella wants me alive." This seems likely to get Edward out of any homicidal-vampire mode towards Elspeth, anyway. At that point, they can escape and finish the exposition later.
