Becky (Katherine Kelly) is left feeling utterly depressed over the festive season when Steve makes the ultimate commitment to scheming Tracy - asking her to marry him and vowing to sell The Rovers so they can buy Lloyd's house and live together as a family.
As Tracy (Kate Ford) has lied to everyone by claiming that Becky caused her miscarriage by pushing her down some stairs, the feisty blonde makes a last-ditch attempt to make Steve see sense - warning him that he's making a big mistake by planning a future with the Weatherfield villain.
When Steve (Simon Gregson) refuses to listen, Becky heads back to her flat alone and begins burning some of their old photos as she drinks destructively.
As Becky falls asleep, she has no idea that the embers are still alight and a fire quickly takes hold. When Nick Tilsley (Ben Price) spots smoke coming from the flat, he kicks the door down and an ambulance is called - but will he reach Becky in time?
These scenes air on Sunday, December 25 at 8pm on ITV1.

Coming up in Emmerdale's Christmas episode, the festive atmosphere turns sour as Debbie Dingle and Alicia Gallagher's bickering spirals out of control.
As Alicia (Natalie Anderson), Andy (Kelvin Fletcher), Cameron (Dominic Power) and Debbie (Charley Webb) all come together for Christmas dinner, Alicia is left fuming as Sarah receives a collection of lavish presents - while Jacob gets nothing in comparison.
Alicia is annoyed further when Diane and Victoria arrive with a gift for Sarah but nothing for Jacob. Mortified by her mistake, Diane gives him a hastily-wrapped tin of biscuits from the kitchen - but Alicia remains unimpressed.
As the Christmas meal begins, Alicia can't resist making snide comments to Debbie and the pair's bickering ruins the atmosphere.
In the end, Debbie gets so sick of Alicia that she pours her Christmas dinner over her head! With tensions clearly still running high over the saviour sibling plan, will things get worse as Debbie does a pregnancy test?

Meanwhile, Hollyoaks' Boxing Day episode sees troubled Doug Carter reach breaking point as he prepares to end it all.
With Texas and Leanne both away for the holidays, Doug (PJ Brennan) struggles to cope as he spends the festive season totally alone.
At his lowest ebb, Doug decides that he'd be better off dead so he drunkenly stands on the edge of a bridge and prepares to jump.
However, just as he does so, Doug finds himself back in his flat with the heavenly vision of Steph Roach (Carley Stenson) before him!
Steph is back as an angel to convince Doug of the positive impact that he's made in Hollyoaks over the past year. She soon shows him a very different world - illustrating that without his influence, one teenage resident would be pregnant, while another character would be a broken man after losing his loved ones at the hands of Silas Blissett.
However, Doug also sees that if he had never arrived in the village, his late girlfriend Bex (Daisy Turner) would still be alive. Faced with the decision of whether to go to heaven and save Bex's life, or return to Hollyoaks and save the fate of his friends, what will Doug do?
These scenes air on Monday, December 26 at 6.05pm on Channel 4.
