The ending of Life On Mars was somewhat ambiguous. So you're saying that Ashes will have a more definite explanation?
"Not only that, but it will also hopefully explain the ending of Life On Mars as well. The idea is to unify the two shows. Series three unifies Life On Mars and Ashes To Ashes and makes them one show. By the time you get halfway through series three of Ashes To Ashes, you will actually feel like you're watching series five of Life On Mars!"
So with that in mind, can we expect Life On Mars characters to come back in Ashes series three?
"Umm... you can!"
