Casualty spoilers: Teddy and Iain risk lives during horror crossbow attack and Nicole rocked by life-changing news

THIS week is set to bring fresh shocks to the emergency ward as personal problems get the better of some staff members.

Here is a rundown of what to expect in upcoming scenes.

Teddy and Iain's brush with danger

The paramedics get an emergency call and rush out to tend to an injured delivery driver.

Once at the house, they are shocked to discover that person is dead, and there is an injured woman on the scene whose ex attacked her with a crossbow.

They attempt to move her to the ambulance, but another crossbow shot is fired, and Teddy and Iain are left not knowing whether to risk the journey.

Faith comes under suspicion

The Advanced Clinical Practitioner was forced to take some time off work when her drug addiction was made public by a patient.

Now she is being phased back into work at the Holby City hospital after having some time away to recover in rehab.

Her joy about being allowed back on the ward slowly fades when she discovers Patrick instructed Siobhan to keep an eye on her.

As part of her job Faith is allowed to prescribe medication to patients, and when a prescription slip goes missing she knows she will be the number one suspect.

Nicole gets a pregnancy update

Nicole is currently carrying a baby as a surrogate for Rosie.

Co-workers became alarmed after seeing Rosie start to exhibit controlling behaviours, such as monitoring the pregnant woman's diet.

Will things get even worse once Nicole gets a phone call informing her that the baby has Down's syndrome?

Teddy lashes out

Teddy is left shaken and overwhelmed after the terrifying crossbow incident but bravely volunteers to ride in the back of the ambulance on the way to the hospital, despite having been recently sexually assaulted there.

However, the emotions take a toll on him, and he ends up getting in a fight with a patient's boyfriend once in the emergency ward.

The situation escalates, leading to him punching the man in anger.

Will he get fired for this aggressive outburst in the workplace?
