It isn't likely at all for a character, who already died in the book before, to suddenly appear again in the next book, at some point in the timeline of this character before. Such a jump back never happened before, if a character died. It would be as strange as Rahvin suddenly appearing in LoC in a scene before his death. Or Sammael being alive in PoD. It doesn't make much sense, especially since BS said that only "Graendal’s name will be mentioned a few times" in ToM.

If Graendal has passed some vital informations to Aran'gar, it simply makes more sense that Aran'gar will remember in a PoV im ToM her last talk with Graendal before she died, where she told this.



Aran'gar probably is that stupid for plot's sake.. But seriously, if Romanda hadn't put it together, likely no one else had seen the connection to Cabriana and Halima.



It probably was Aran'gar's plan.



That was before Aran'gar was forced to leave the Rebels, though. Like Aran'gar was previously commanded by SH to join the Rebels, it simply makes sense that he gave his "dagger" a new task to spread chaos, after she had to quit that job.




No, I think Graendal just knows that Mesaana must be an AS, but not who exactly.
