Full Casualty spoilers for Supply and Demand - Episode 8 below…

Jacob Masters stands his ground

Paramedic Jacob Masters (Charles Venn) is understandably seething as he’s put on desk duty while an investigation into whether or not he stole morphine supplies gets underway this week. And, adding insult to injury, Iain Dean (Michael Stevenson) is covering his shifts!

Their boss, Jan Jenning (Di Botcher), does her best to calm the stormy waters, but it’s no easy feat with tension brewing and emotions running high.

Arresting development

As Iain’s shift gets underway, shocking events at a shout out in an underground carpark (see below for more) lend weight to his developing theory that the morphine being supplied to the paramedic crews is most probably being tampered with.

Desperate to right wrongs, Iain persuades Jacob to join forces with him to prove his suspicions, and the results are horrifying…

Faith no more?

Prior to this, in an exchange between Iain and his new wife Faith Dean (yes, we’re officially calling her Mrs Dean now!), the advanced clinical practitioner remains unconvinced of Jacob’s innocence.

Initially Iain’s frustrated when Faith (Kirsty Mitchell) defends her position, but later, based on her hubby’s discoveries, she’s forced to admit she got it wrong.

Feeling terrible Faith heads over to the ambulance station to apologise to Jacob at the earliest opportunity, but he’s not interested in anything she has to say.

It’s also clear that Iain is furious with Faith. In a heated exchange, words are said that cannot be unsaid and big cracks appear in their relationship.

Morphine thief revealed

Meanwhile, hurting from being accused of a crime he didn’t commit, Jacob thaws towards his (former?) bessie mate Iain as they work together to irrefutably prove his innocence.

Speaking about the future for the friends Charles Venn, who plays Jacob Masters tells WTW: “You want to believe that they’ll figure it out eventually, like brothers. It's that whole thing of you might not be happy, it may take a minute, but deep down you want to resolve it, and you just hope it's a case of not if, but when.” Full interview available here

But even so, their bromance is still broken, and Iain’s marriage to Faith is on pretty shaky ground now as well.

There’s a shock twist too — as they inch closer to the truth, the identity of the real culprit is revealed to viewers!

Nicole and Cassie - tragedy strikes

Another major storyline this week revolves around doctor Nicole Piper’s attempts to help vulnerable Cassie Woods escape the criminal drug gang that’s been making the young woman’s life a misery.

The story kicks off with both women on pins as they count down the hours until Cassie (Charlie Ann Upton) hops on a one-way train to Newcastle to stay with a close friend of Nicole’s.

However, when Nicole (Sammy T. Dobson) must go into work at the last minute, Cassie decides to leave the safety of the flat to buy her a goodbye gift.

We don’t want to spoil what happens next, other than to say that there are shocking scenes after Cassie is brutally attacked while walking through an underground carpark and is raced to Holby ED.

As her life hangs in the balance, Nicole reaches out to social services for additional support for deathly ill Cassie and opens a Pandora's box on her own painful past in the process…

Speaking to WTW on the set of Casualty, Sammy T. Dobson, who plays Nicole Piper reveals: “It’s an intense situation. Cassie is many things to Nicole and it’s like she’s looking at her younger self.” Full interview coming soon. Check back for updates

Nicole opens up to her ex, nurse Ngozi Okoye (Adesuwa Oni), about her childhood, revealing that she grew up in care after her mother gave her up when she was four-years-old.

There appears to be a glimmer of hope for the former couple in that moment, until Ngozi reveals a shocking secret of her own…

Elsewhere, consultant Dylan Keogh (William Beck) is privy to Ngozi’s decision and gently advises her to reconsider!

Nurse Cam Mickelthwaite (Barney Walsh) considers whether or not to forgive a friend.

Paramedic Indie Jankowski (Naomi Wakszlak), however, is not in such a forgiving mood when it comes to Cam. Sensing the tension Teddy Gowan (Milo Clarke) attempts to play matchmaker.

Will he succeed?

And, finally, doctor Rash Masum (Neet Mohan) is feeling slightly daunted as he faces a difficult shift on his first day off antidepressants. Fortunately, nurse Rida Amaan (Sarah Seggari) is on hand for support and encouragement. And Rash ends up needing her advice after pharmacist Sunny Callahan (Jamie Marie Leary) excitedly reveals she's ready to take their relationship to the next level…

No, not that!

She invites him over to hers for a takeaway and to meet her teenage son Jake (Gabriel Goulding, The Kitchen).

At first Rash agrees, but then gets cold feet. Is he ready to face his fears, or will he end the budding romance in its tracks?

Sunny smiles at Rash as he visits her at the hospital pharmacy.
