CORONATION Street's Gary Windass has been heading down a dark path of late after MURDERING Rick Neelan and taking on his role as the Street's loan shark.
But ahead of the mass shooting on Christmas Day, Ian MacLeod has confirmed that the devastation will be a wake-up call for the former builder.
Will Gary Windass kill again in Coronation Street?
But things really kicked off when Gary ended up killing loan shark Rick after he threatened to hurt his then lover Sarah.
Gary then took over the role of the cobbles' loan shark, beating up a number of residents including Ryan after he was unable to pay up.
Fans of the ITV soap will also know that the bad boy then found a safe brimming of money in a storage unit belonging to his murder victim.
Gary has been rebuilding the Underworld with the money , but has been keeping his funds a secret by using his stooge Derek as a cover.
The killer has been claiming Derek is a rich businessman who's invested in the factory even though he is actually one of Rick's clients.
However, things haven't quite gone to plan for the shady builder.
Derek has sold the factory -which though belonging to Gary is under his name-to Nick and Sarah.
Could a furious Gary end up killing Derek?
Corrie boss Ian MacLeod has spoken out to say that Gary probably won't end up murdering anyone on the Street.
Why happens to Gary on Christmas Day in Coronation Street?
The tables turn on the evil loan shark-who's been controlling Derek for months-when his stooge sets out on a violent gun rampage.
Spoiler pics show Derek bursting into the Rovers and holding Gary at gunpoint.
Gary then lures Derek into Winter Wonderland to avoid the pub guests getting involved in the crossfire but puts other residents in danger.
Derek looks worse-for-wear as he goes on his rampage around Winter Wonderland searching for Gary as the rest of the residents take cover in the festive fairground.
And Corrie has confirmed that the lives of two residents will be left hanging in the balance.
What has Corrie boss Ian Macleod said about Gary's descent to the dark side?
Ian MacLeod spoke to the Metro about Gary's descent to the dark side: "Gary did come into the show among a family who were described as the Sopranos of Weatherfield a very long time ago and he was a right old ne'er-do-well .
"We did gentrify him over the years and put him in a pair of metaphorical slippers."
Ian went on to insist that Gary isn't all evil: "One thing he's never been is an out and out murderer. He's not Phelan.
"He never intended Rana to die and Rick, he did kill to some degree in self-defence but also because he knew if he let him loose, he would kill Sarah, the person he totally loved at that time.
"Those were the worst things he is capable of. I don't see him transitioning into a cold blooded murderer at all."
Ian spoke about the upcoming disaster on Christmas Day, and revealed how the event will be a wake-up call for Gary: "Christmas is huge and somewhat triggered by Gary's descent to the dark side.
"This will provide him with a massive wake up call. As he tries to rationalise the terrible things that have happened, he's unable to talk himself out of his guilt.
"His experiences with Rick have changed him permanently-he won't ever go back to cuddly Gary Windass who takes Jake to the park.
"He'll still do this but his experiences have changed him permanently into a slightly darker character."
