Oh, wait. That`'s my job.
Is Willow not in the room that Aggie just lead everyone into?
It'd be crazy weird for Cal to respond to Kara by ringing Willow up if the woman is physically right in front of them.
I figured most of the major hoo-doo types would be with Doom, both to work with him on the major magicks and to keep an eye on him (I doubt they trust him further than they can spit, naturally so). Aggie would assume the same I think.
Plus it'd be rather rude to have new comers drop by and not introduce them to the ruler of the land and owner of the castle they so casually entered. Aggie was brought up with proper manners after all, even if she puts her own spin on things.
I'm also guessing as many or more versions of heaven and the upper planes merged together too. Which isn't necessarily a bad thing for the prime material plane, as they're too busy figuring things out (one way or another) to cause too much havok there!
With the luck folks in the Merge universe seem to have... fused-heaven could just be empty, saint of killers might have finished off everyone up there like months ago.
