Louise Mitchell is set to stun the Taylor family following EastEnders' brutal Christmas Day episode.
This year's gloomy festive special saw Ben Mitchell (Max Bowden) pressuring an already-distraught Martin Fowler (James Bye) seemingly into shooting Keanu Taylor (Danny Walters) as revenge for his affair with Sharon Mitchell (Letitia Dean).
Perhaps the most jaw-dropping part of the Mitchells' revenge plot was that Phil (Steve McFadden) convinced Keanu's fiancée Louise (Tilly Keeper) to go along with the plan to take him out.

A first look at EastEnders' Boxing Day (Thursday, December 26) episode reveals that Louise will go one step further by returning her engagement ring to Keanu's mum Karen Taylor (Lorraine Stanley).
With Louise having taken this surprisingly bold move, there are still no answers over whether Keanu is alive or dead after his violent encounter with Martin.
What to Read Next
Tilly Keeper previously hinted that Louise would indeed have an unexpected reaction when she learned that her partner had a fling with her stepmum Sharon.
"It's a reaction I don't think anyone will expect," she said. "Of course, she's a young girl and her fiancé has cheated on her, so she's obviously devastated."
Keeper is set to leave Albert Square at the conclusion of this volatile storyline, as is Keanu actor Danny Walters.
EastEnders will air Louise's confrontation with Karen Taylor on Boxing Day (December 26) at 9pm on BBC One.
