Holby fans were left stunned recently when Professor John Gaskell killed his friend and colleague Roxanna MacMillan via lethal injection, amid fears she’d expose his risky medical practices relating to his precious stem cell trial.

As Roxanna’s funeral is held this week, grieving surgeon Henrik Hanssen (Guy Henry) tries to support the medic through his own loss, unaware of Gaskell’s involvement in their friend’s death. But there’s no time for mourning as Jac Naylor (Rosie Marcel) needs their combined expertise on a case.

Holby, Roxanna, hospital

Holby City

A builder has sustained life-threatening injuries in an accident with some scaffolding poles, and Gaskell and Hanssen must work together with Jac to save his life. Gaskell, however, becomes visibly irritated in theatre as Hanssen reminisces about their wonderful friend and skilled surgeon, Roxanna.

He then gets annoyed as Hanssen mentions Roxanna’s involvement in the Julie Bloom case, which was the catalyst in Gaskell’s drastic decision to silence her. Gaskell’s always strived to do his best by his patients – but as the builder develops severe bleeding, Hanssen’s suspicious when Gaskell questions whether it’s worth saving him.

As the builder continues to bleed out, the Professor physically tries to stop Hanssen from saving him, saying they should let the man ‘die with dignity’. Jac’s furious and orders Gaskell to leave theatre!

Later, concerned about his friend’s mental state, Hanssen asks him if there’s anything he can do to help and he reminds him that he can’t bring Roxanna back. Will Hanssen realise these are the words of a guilty man?
