Continuing our rewatch of Series 2 brings us the long awaited two-part return of... Pete Tyler! Also I guess the Cybermen... whatever Boomer (scoffs)... Whilst “Rise of the Cybermen” lands us in an alt-universe London where their Rose is a dog, Mickey is gay, and our Doctor reunites with his Potterverse father. “The Age of Steel” kills off alt-Jackie, Rickey (alt-Mickey), and the rising alt-Cybermen. You just know this Doctor is not unhappy about some of these developments.
