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…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!
