It’s been almost two years since Sam Mitchell last graced our screens, fleeing EastEnders after severing ties with brother Phil and the Mitchell clan. But Sam may need her family now more than ever, when she returns to Albert Square as part of an important and emotional new storyline.
Sam faces a breast cancer scare after she discovers a lump. It’s her late mother Peggy Mitchell’s own battle with the disease, and her death in 2016, that leaves Sam convinced it’s serious.
Actress Kim Medcalf shared: “This is the second time Sam has found a lump in her breast and 20 years ago, she felt very lucky that it wasn’t anything serious. This time Sam assumes it’s going to be a different outcome because of Peggy’s history. Sam feels like the same thing is going to happen to her and so she’s putting her head in the sand.”
Hiding her turmoil from her loved ones and refusing to be checked by a doctor, Sam instead begs her brother Phil for money. Viewers will recall that the pair aren’t currently on good terms, given last year her dramatic exit saw her expose his affair with Emma Harding to the entire Square.

“She’s nervous, especially how things were left with Phil!” Kim revealed. “But then again, Sam’s not the kind of person who spends a lot of time thinking about the past, she lives in the moment.”
Kim teased that Nigel Bates, who revealed his devastating dementia diagnosis earlier this year, soon gets caught up in Sam’s scheming too. As Sam attempts to steal money from Phil’s safe, Nigel lets her, after sadly mistaking her for his daughter Clare.
Of course scheming Sam avoids correcting him, but it’s not long before her brother realises the truth. Sam will attempt to flee once more with the cash, before confiding in former flame Jack Branning, son Ricky’s dad, about her health secret.
Kim hopes this will lead to Sam seeking help, as she shares the importance of getting checked early. “We all need to encourage each other to regularly check our breasts because if you can catch breast cancer early enough, it can make a big difference to the prognosis and treatment,” Kim said. “To be given a storyline where I can play a small part in raising awareness is a real privilege. As a woman in my 50s, it’s something me and my friends talk about because we all know people affected by breast cancer and it feels very relevant and important.”

Of course Sam’s long-awaited return to the soap will also see an exciting reunion fans have been desperate for, between herself and Zoe Slater. The last time they were onscreen together back in 2005, the pair, joined by Chrissie Watts, were involved in the brutal murder of Dirty Den, who was buried under the floor of The Queen Vic.
Sam was sent to prison over the death, while the pair believed Zoe killed Den during their violent showdown. She was soon released though when Chrissie’s guilt was unearthed, while Zoe fled Albert Square until her own comeback earlier this year.
It’s safe to say Sam isn’t thrilled by the reunion, and it will open up some old wounds for both characters that they would rather remain closed. Kim explained: “Coming face-to-face with Zoe is triggering for Sam and brings up a whole series of memories that she’d much rather forget.”

It leads to Zoe wondering if Sam is behind her ongoing stalker ordeal, and a showdown ensues. “You can’t blame Zoe for suspecting Sam, they’ve got history!” admitted Kim. “They both shared this terrible experience that traumatised them in their own different ways.”
Kim confirms though that her character has nothing to do with Zoe’s torment. “Sam is adamant that she’s got her mind on other, far more important things. I think Zoe is convinced by Sam’s protests, but Kat isn’t quite so sure about her.”
Kim has loved the chance to work with Michelle Ryan, who plays Zoe, again two decades on from their iconic plot. “It has had us taking a trip down memory lane to remember where our characters were when we were last in the show, and what was going on in our lives in Walford,” Kim shared. “Having this chance to reminisce together has been lovely.”
