Did they ever say what WWW stands for?
Skarosa heard three words from the afterlife: Don't Cremate Me. Those are the "three words" that change peoples life.
Crap..."Don't cremate me"...The Master...could it have been The Master screaming through the pyschic link when 10th burned his body?
Possibly, but he had already dumped his consciousness into his ring. Not sure how it all plays together.
My wife and I had a running bet about Missy's identity. She thought it was the Great Intelligence, I thought it was the Master. The Doctor's face when he felt Missy's heartbeat told me what I needed to know. A damn shame the bet wasn't for money.
So now... the Cyberman in the room with Clara. Is it Danny? Did Missy's activation of the tombs upgrade Danny before he could dump his humanity? And what of Danny Name-Is-The-Same-As-His-Shirt-Colour? How does Clara descend into Cyber hell to retrieve her beloved? Or is this where she realises the price of travelling with the Doctor is too high?
