not sure if we will hear much from Pycell--Cersei demoted him down to creepy old man; no longer creepy old man with influence.
BTW--I really like Pycell and especially the actor portraying him. I still think of that scene in season 2? where he's finished bedding the whore, goes on rambling about nonsense as he usually does, and as soon as she leaves, he drops his eternal old man act for a few moments to stretch and get ready. Then he puts on his robe and wizard hat, reintroduces the hunch, and saunters out of his chambers. Epic.
Ever see the delete scene with Tywin and Pycelle? More of the same stuff.
