Next week on Casualty, ex-EastEnders star Nigel Harman makes his debut as Dylan's old rival Max, while Robyn makes a life-changing decision and Stevie seeks comfort in Marcus.

Here's a full collection of the biggest moments to watch out for:

1. Meet Max!

Former EastEnders star Nigel Harman will be making his first appearance next week, and fans will meet his character Max out at the site of train crash ? where he is trying to help a young girl.

As Max makes his way into the ED, it quickly becomes apparent that he has a history with Dylan ? who is far from pleased to see him.

2. Robyn panics over her relationship with Paul

It's Paul's first day training to be a HCA and he is supported by Robyn, who is brimming with pride.

When Paul tells Robyn that he has something he wants to ask her, Stevie jokes that he's about to propose.

Robyn is horrified by this and immediately dismisses the idea.

3. Stevie's problems escalate

Stevie is horrified when she realises she's been regulated to minors, but Marcus insists that he's simply trying to 'help her.

Marcus claims that thinks Stevie should be keeping a low profile following another complaint, especially as the press are showing an interest following the incident in the area.

4. Robyn and Paul make a life-changing decision

With Stevie's words ringing in her ear, Robyn gets the wrong end of the stick when Paul gets down on one knee.

Hurt by her reaction, Paul tells Robyn that he was actually going to ask if she'd consider moving back to Wigan with him, but clearly she's not ready.

As Robyn reflects on her conversation with Paul, she is touched to see just how much effort he's gone to in order to make this a reality.

Robyn later makes a life-changing decision, but what is it?

5. Max threatens a patient

Max and Faith treat a 16-year old victim of the train crash, who initially comes in with a dislocated shoulder. It doesn't take them long to realise that the teenager is having a miscarriage, and Faith starts to suspect that she's been groomed by her football coach.

After acknowledging Faith's concerns, Max takes matters into his own hands and attacks him ? infuriating Dylan in the process.

6. Stevie seeks comfort from Marcus

After ignoring a patient's request for a male doctor, Stevie's problems go from bad to worse when she doesn't diagnose him in time and he dies.

Devastated, Stevie seeks comfort from a manipulative Marcus and they share a kiss.

7. Max drops a bombshell

At the end of a difficult day, Dylan is glad to see the back of his former rival, Max.

He's shocked, however, when Max makes it clear that he isn't going anywhere ? Marcus has asked him to step in as Acting Clinical Lead.
