Stevie Nash (Elinor Lawless) is back at work in tomorrow’s episode of Casualty, but it soon becomes clear adapting after her cancer journey is going to be tough.

She is supported by friend Flynn Byron (Olly Rix) as she gets settled back into life at the ED, but Stevie ends up breaking down after a difficult shift, admitting that she doesn’t know who she is anymore.

As the week continues, Flynn cheers Stevie up by going swimming with her. They race in the pool and it makes Stevie smile, but Flynn then royally puts his foot in it by trying to kiss his mate.

Elsewhere in the ED, Nicole Piper (Sammy T Dobson) gets a surprise visitor, and Teddy Gown (Milo Clarke) makes a decision about his future as a paramedic, as the dynamic between Team 3006 remains fractured.

Here’s everything you need to know about Saturday’s (June 21) episode of Casualty.

Stevie returns to work

Stevie is back at work but she’s putting on a brave face. On her first morning back in the ED, Stevie walks into chaos as overdose patients flood the department. Flynn welcomes Stevie back and they jump into the deep end together in Resus. The countless OD patients keep them so busy, Flynn has to leave Stevie on her own.

When Flynn returns, he spots Stevie’s hands trembling. He takes over and later asks his friend why she didn’t mention the problem and she breaks down, telling Flynn that she’s sick of being seen as a warrior.

As far as Stevie is concerned, she didn’t fight cancer – she just survived it. Stevie admits that she’s scared all of the time, and doesn’t know who she is anymore.

Flynn ruins a moment

The next day, Stevie and Flynn find Dylan Keogh (William Beck) standing among the body bags of the patients from the last 24 hours. Stevie and Flynn spend the day together again and then enjoy a few hours of swimming. Stevie smiles while being with Flynn, due to the fact it’s the first day she hasn’t woken up with pain in her hands.

They enjoy a genuine moment, but Flynn ruins it by trying to kiss Stevie.

Nicole faces someone from her past

Nicole’s foster mother Maggie arrives in the ED and asks her to look after Cassie, her foster daughter. When Maggie dies, Nicole refuses to entertain the idea of Cassie living with her. That evening, Nicole sees Cassie getting into a suspicious looking car outside the ED, but will she give in and let Cassie move in?

Ngozi continues to spiral

As her struggle continues, Ngozi (Adesuwa Oni) heads to the pharmacy to collect the morning after pill. Nicole, who is watching this unfold, is upset to realise her ex is having sex.

Teddy makes a decision

Following Iain Dean’s (Michael Stevenson) secondment offer at Hart, Faith (Kirsty Mitchell) tries to enlist Jan (Di Botcher) in a bid to persuade him to not go. However, Iain sees time at Hart as his calling, so Jan accepts the decision.

Unfortunately, she’ll be in for another surprise when Teddy decides to join Iain for the trial, frustrated at the tension between the paramedics.

Rash’s romance

Rash (Neet Mohan) continues to enjoy Sunny’s presence at the hospital but when he tries to ask her out, it goes disastrously wrong and he chickens out!
