Rash Masum learns the terrible truth

Rash Masum (Neet Mohan) is in for a shock this week when he learns his girlfriend is stealing drugs from the hospital.

The dramatic developments are set in motion when Jan Jenning (Di Botcher) embarks on a mission to identify Holby’s morphine thief. Suspecting the culprit works in Holby’s pharmaceutical department, the paramedic pays a visit to chemist Sunny Callahan (Jamie Marie Leary) and almost catches her in the act.

Realising something’s amiss Jan is about to investigate further when they’re interrupted by the arrival of cheery delivery driver, Terry Melville (Bill Fellows, Coronation Street, Whitstable Pearl), an old friend, who clearly holds a torch for the medic!

Later, still determined to get to the truth and unable to shake the sense that Sunny is hiding something, Jan turns to Rash with her suspicions…

Rash’s decision

At first Rash is shocked and defends Sunny, but over the course of the shift it’s clear she’s on edge and, when she makes a near-fatal error with a patient that’s been stung by a scorpion (see more below), he asks her to tell him what’s going on.

But he soon wishes he hadn’t!

Sunny finally opens up and reveals she has serious reasons for doing what she's doing - the violent drug gang have her son Jake (Gabriel Goulding) and are threatening to hurt him.

Distraught, Sunny begs Rash to keep her secret and not report her.

Will he help cover up her crimes?
