Yasmeen Metcalfe's brutal attack on her husband Geoff was planned from the start, according to Coronation Street producer Iain MacLeod.
In this week's episodes, Geoff's coercive control over Yasmeen reached a horrific crescendo, which saw the former sliced across the neck with a broken bottle after an argument.
Whether or not Geoff survives is still a mystery, but MacLeod promises Yasmeen's actions have always been part of the wider plan put in place by the writers.

He recently told Radio Times: "It's been refined month by month in conjunction with our charity and research partners (including Women's Aid). We've known pretty much from the start this incident would be one of the major peaks.
"It's been organically told and we've agonised over the advancement of how Geoff's behaviour evolved.
What to Read Next
"It has been discussed in more detail than any other story I've worked on, just to make sure we get the nuance right."

MacLeod also shared how there's been some "amazing feedback" from viewers who've experienced similar abuse throughout their lives.
"We don't make it for this reason but it is important to have what I call good 'drama karma': what you're putting on screen is karmically making the world little bit of a better place. I really think this story is."
Coronation Street currently airs on Mondays, Wednesdays and Fridays at 7.30pm on ITV.
Organisations including Women's Aid can provide further support and information on coercive control or coercive behaviour.
