I think Moghedian is pulling strings in Caemlyn as well as running errands for Moridin

I believe Halima ran off to the BT. There's a coming fight between the White and Black Towers in ToM and I think we'll find Halima involved. Clearly lots has been going down at the BT - AS probably bonded to DFs/Dreadlords and I think it's likely that there are 13 Myrdraal on hand to make things particularly interesting.

Not that you asked, but I think Cyndane is hunting for Mat and Perrin - she's probably behind Masema and was the forsaken coming to him in 'visions'. There's probably some complusion involved as well.
