Doctor Who: 8 Big Questions After Time Heist

2. What Do The Sensorites, Aliens Of London And Torchwood's Kiss Kiss, Bang Bang Have In Common?

It's a blink-and-you'll-miss-it moment, but a huge one for Doctor Who fans. In his desperate attempt to save Clara by giving himself up to the Teller, Psi hacks into the bank's computer and demonstrates why he is in the criminal big league. In essence, why he deserves to die more than Clara. We've already talked about the mystery behind his character. This question is all about those criminals he associates himself with. The Sensorites, an alien race not seen since the very first series back in way back in 1964. The gunslinger from the seventh series's A Town Called Mercy. The Ninth Doctors 'love-them-or-hate-them enemy the Slitheen. The ice warriors and surprisingly James Master's Captain John Hart from series two of Torchwood. Is there a connection between them? Or are they simply a host of intergalactic criminals considered a threat to the Bank Of Karabraxos? Either way, Time Heist played deep into Doctor Who history to add some depth to the universe outside Karabraxos. Perhaps we'll get a chance to visit that criminal underground in the future. Who wouldn't want a return of Captain John Hart to the Doctor Who universe?
