Moment of truth! Sickened by her actions, Archie decides to come clean. Can Will convince her otherwise?

Doctor Archie Hudson is shaken to her core when former patient Vincent Millbank is admitted to the ED.

Archie (Genesis Lynea) believed she was off the hook for vandalising Vincent’s car after consultant Will Noble charmed a security guard into destroying CCTV evidence of Archie pouring acid over the retired teacher’s classic Jaguar. Viewers already know that Archie’s actions were a result of learning Vincent (Tim Woodward) remorselessly bullied his former pupils, driving one to suicide.

Squaring up… Rash feels it’s his duty to report Mason. Mason disagrees!

Doctor Rash Masum’s intentions to focus solely on his own career get derailed fairly quickly this week. Rash takes matters into his own hands when he discovers junior doctor Mason Reede is covering up a catalogue of mistakes – one which caused the death of an elderly patient.

Horrified Rash decides to report Mason to consultant Ethan Hardy, although pinning the senior medic down turns out to be tricky (see below).

Ironically, after Rash’s career being jeopardised by the junior doctor’s lies, Rash now holds Mason’s future in his hands…

Could this be an opportunity for revenge?

Theo threatens to expose Ethan (Oh err missus) unless he finds out which trial group Effie’s been placed in. Yes, it’s another fine mess Ethan’s gotten himself in to!
