EastEnders fans are saying they’ve ‘worked out’ who Nicola Mitchell’s sister is after hearing her ‘heartbreaking’ backstory.

The former wife of Teddy Mitchell was introduced to the BBC soap in November last year, several months after her family arrived.

Instantly becoming a fan favourite character, it soon emerged that Laura Doddington’s Nicola was hiding some dark secrets from her past.

Viewers were stunned earlier in the year when it emerged that Nicola had killed her son Harry Mitchell’s girlfriend Shireen Bashar, who had been missing for three years.

On top of this, Nicola admitted that Zack Hudson was her teenage son Teddy’s biological father after cheating on Teddy in the past.

Recent weeks have seen Nicola growing close to George Knight, with the pair sleeping with each other last month.

In scenes that aired on Tuesday night (August 19), Nicola was struggling with her emotions on the anniversary of her father’s death.

Despite Teddy advising George to stay clear of her, he decided to take a break from his brother Kojo Asare’s birthday to compare notes about their past.

“The other 364 days in the year, I don’t give him a second thought. I don’t let myself. This is the only day he gets, and that is more than he deserves.

“He used to like to show me off, down the park or whatever. He’d stop and talk to people, and I’d just have to stand there looking pretty, being well behaved.

“And if I wasn’t, when I got home I’d feel the back of his hand. And then, he’d just ignore me. Sometimes for days. One minute, he was this proud dad, and then the next, he couldn’t even look at me,” Nicola said in tears.

Nicola went on to say that while she was grateful for her mum and sister, her dad ‘got worse’ as he got older. Following their heart to heart, Nicola and George once again united in passion.

Despite Nicola previously going to Ibiza to spend time with her sister, fans on X are now convinced that the referenced character will appear in Walford, with some believing they know who she is.

I’m really hoping they continue this and decide to bring in her mum & sister soon.”

@RyanSoapKing25 commented: “#EastEnders A heartbreaking scene between Nicola and George. Nicola opening up to George about her upbringing and her unstable relationship with her father. I’m pleased that we’re finally getting an insight into Nicola’s past – now bring in her sister or mother.”

For those who don’t recall, Vanessa Gold appeared on EastEnders for just one year between 2010 and 2011. Played by Zoe Lucker, the character is best known for love triangle with Max and Tanya Branning, as well as her ‘bubbly’s in the fridge’ meltdown.
