Spoilers for Face the Raven, Heaven Sent and Hell Bent

Face the Raven

Clara probably never expected her friend Rigsy to need the emergency TARDIS phone number she gave him after they defeated the Boneless in Bristol. Yet today he’s in big trouble, sentenced to die for a murder he can’t remember committing. The Doctor and Clara’s campaign to exonerate Rigsy leads them to a secret London street where alien refugees hide in plain sight. Once they gain access, they’ll learn the terrible answers to various questions. Such as: what is a chronolock? And what exactly does it mean to face the raven?

Heaven Sent / Hell Bent

Long before the Time War, the Time Lords knew it was coming. Like a storm on the wind. There were many prophecies and stories. Legends before the fact. One of them was about a creature called the Hybrid: half Dalek, half Time Lord. The ultimate warrior. But whose side would it be on? Would it bring peace, or destruction? Was it real, or a fantasy?

“I confess: I know the Hybrid is real,” the Doctor proclaims. “I know where it is, and what it is. I confess: I am afraid.” ( x )
