According to Kate Stewart, the jarring shift from Conrad's World back to normal reality resulted in the new world having several minor changes compared to how it originally was. Among these changes was that Ernest Borgnine, who had previously been dead, was now still alive, with Belinda Chandra remarking that Ernest had "got lucky". (TV: The Reality War)
Behind the scenes[]
In the real world, Ernest Borgnine, an American film and television actor, passed away in 2012, and it can be assumed that his Doctor Who universe counterpart had originally passed away at a similar point. In this timeline he would be at least 108 years old, being born in 1917.
