Also known as WAY TO BREAK MY FUCKING HEART, RUSSELL T. DAVIES.

I only have a few words to say about this one: Toshiko Sato, you did good. You did very, very good. Rest in peace, our favorite nerdy, socially awkward, completely brilliant Torchwood staffer. 

As for Owen? Nobody will confirm that he's really dead, but honestly if he got dosed with a crapload of radiation, he might wish he were dead. That stuff is harsh. 

However, I think RTD made up for the heartbreak this episode was by offering us Partners in Crime the very next day!
