Coronation Street boss. Iain MacLeoad has teased what's next for Gary Windass after the dramatic Christmas siege.

Weatherfield is set to be rocked next week as the builder-turned-loanshark's feud with Derek Milligan boils over. Derek believes that Gary Windass has ruined his life - and is determined to make him pay. And when Fiz accidentally leaves an antique rifle in Gary's furniture shop, Derek heads to the Rovers with a mission: to hunt him down. After a seasonal showdown at the pub, Derek chases Gary onto the cobbles and the pair end up coming to blows on the Helter Skelter - and as the fists and bullets start flying, there are fatal consequences for one of the residents. MacLeod revealed to Metro that the Christmas Day tragedy will end up being a wakeup call for Gary. "Christmas is huge and triggered somewhat triggered by Gary’s descent to the dark side. This will provide him with a massive wake up call. As a he tries to rationalise the terrible things that have happened, he’s unable to talk himself out of his guilt," he said. "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 that but his experiences have changed him permanently into a slightly darker character."
