In the episode ‘Time Heist’ the Doctor and Clara must break into the most secure bank in the universe – the Karabraxos Bank – along with two other people: Psi, a hacker with an augmented brain; and Saibra, a mutant humanoid with the ability to shapeshift.
Only the Doctor and Clara make it past the head of security, Ms Delphox (Keeley Hawes), and the alien Teller.
When they break into the vault they are startled to meet Madame Karabraxos (Keeley Hawes), the owner of the bank who looks exactly like Ms Delphox. It turns out that Ms Delphox is one of several clones of Madame Karabraxos: the only people she can trust to help run her business.
Karabraxos packs some valuables in a case and begins to leave to escape an intensifying solar storm. The Doctor gives her his phone number and tells her to call him when she is very old and filled with regret.
