In a parallel universe, Rob Tyler was the son of Pete and Jackie Tyler and a male counterpart of N-Space's Rose Tyler.
Rob was gay, and was in a relationship with Mickey Smith.
Rob met his counterpart, Rose, in London, and questioned her lack of an umbrella given the constant, heavy rain on his Earth. He offered Rose some chips, and took her to a café where they discussed the effects of global warming, the need for renewable energy, and the ban on post-Second World War technology. Rob believed that extraterrestrial interference was a likely factor in the drastic change to the environment.
Rob took Rose home for dinner. Rose realised her connection to Rob once she met Pete, and revealed her status as a traveller between universes. (AUDIO: The Flood)
