I just watched "Time Heist" (S08E05), and I don't understand why the Doctor and his team needed to wipe their memoriesTime Heist ?(S08E05). At the end of the episode, we learn that
the Doctor set up the heist, including wiping his own memory
He prepared all thisin order to
to free the second Teller
SoWhy was the Doctor's memory wiped? Why couldn't
Thethe first Teller could have read their thoughts and just letallow them do/helpto carry on, or even help them ?
Why would he do that ?
