McKee had previously told Digital Spy: "Well, Louise might not be dead! That's the exciting twist in the future....On screen, you'll feel like she's dead but depending on me and whether I want to come back for an episode in March — I might be back. I filmed an extra scene showing that I'm still alive. There are flashbacks which show me being killed, but then there's a flashback which viewers won't see for a while, that will be used if I choose to come back for the episode. I kind of want to come back and finish off Louise's storyline, but at the moment, I might be doing something else. It would be really good, though — I'd be going back to kill a few people off."
