Casualty spoilers: Rash hits rock bottom after horror bus crash and Stevie haunted by traumatic flashback

FANS can expect another wild week on Casualty as Rash faces a family tragedy and Stevie is reminded of a traumatic memory.

Rashid has been struggling to deal with his dad's vascular dementia diagnosis, and things are set to get worse for the father and son in this week's episode.

Viewers will see the doctor take a day off work in an attempt to spend some time watching the cricket with Ashok.

Sadly their bonding experience is ruined when the man has a bout of aggression and locks himself in the bathroom, spewing vitriol at his son.

Rida reassures Rashid that it's his dad's illness talking and he doesn't mean the cruel comments.

A sad Rash returns to the Holby City Hospital to distract himself by working.

While treating a man called Wyatt who is vomiting and has a fever, the doc becomes concerned that the infirm man has Ebola.

The virus is spread by physical contact, and because Rash wasn't wearing PPE while checking his symptoms, if the patient is diagnosed with the illness there is a big chance the doctor has already contracted it.

Other Casualty stars agree he should be put in quarantine as Ebola can be fatal.

Meanwhile Rida gets ready to take his dad to the cricket game, but is horrified to find Ashok gone and his front door left open once she has finished her preperations.

She rushes down to the cricket field to search for him but sees no sign of the old man.

Back at the hospital, the nurse hears that someone who matches Ashok's description has brought into the emergency department for treatment after being hit by a bus.

Rash realises that he misdiagnosed his patient and is released from quarantine in time to hear the devastating news.

The poor man rushes to his dad's beside, overwhelmed with worry.

Meanwhile, elsewhere in the ward, Stevie spots an Ulster Defence Association tattoo on a patient she is treating.

This triggers a flashback to a traumatic event, leaving her shaken.

Faith tries to check if the clinical lead is okay, but Stevie brushes her off.
