Also in Casualty this week

Paramedic Teddy Gowan and student Indie Jankowski treat evasive patient Paris Wythenshawe (Terrelle Kay) when she has breathing difficulties.

While waiting in an ambulance queue outside Holby Hospital, Paris’ dodgy boyfriend Andy Stevenson (Joshua Whincup, Hijack) does a bunk shortly before she goes into cardiac arrest. With rookie Indie (Naomi Wakszlak) too panicked to treat the woman, Teddy (Milo Clarke) takes over and stabilises her just in the nick of time.

Now Teddy’s got questions for Indie! The newcomer confesses that she’s not yet passed her cardiac care module but begs Teddy not to tell their boss Jan Jenning (Di Botcher).

Given he’s just been assigned to mentor Indie and Jan is his aunt, what will he decide?

Junior doctor Nicole Piper (Sammy T. Dobson) is burning the candle at both ends as she takes on extra shifts while attempting to support her friend Rosie Cornwall (Nicola Chegwin) and new baby son Nicholas.

During this week’s fraught shift, Nicole takes a shine to aid worker Chris Stonall (Howard Ward, Little Boy Blue, Downton Abbey), who has not long returned from working internationally in refugee camps. But as Chris’s condition worsens and his son Niall (Simon Shorten, My Policeman) turns up, she realises that all is not what it seems…

And she’s not the only one!

Those closest to Nicole have an inkling that she’s struggling, but by the time the credits roll, viewers alone will get a unique and shocking insight into what the medic is truly experiencing…

Acting Clinical Lead Siobhan McKenzie (Melanie Hill) pulls nurse Jodie Whyte (Anna Chell) aside before her shift starts and shows the junior medic a damning newspaper article about consultant Dylan Keogh (William Beck).

In the piece written by grieving father Aaron Bayliss (Jack Wilkinson), the journalist blames Dylan for the death of his wife. Jodie, however, is deeply relieved that her name isn’t mentioned – and with good reason!

Later, Aaron calls the nurse and asks to see her and Jodie agrees – to best friend Rida Amaan’s disgust.

When Jodie meets Aaron at The Anchor, he makes her a questionable proposal…

What does he want and will she agree?

Meanwhile, as news of Iain’s plight reaches the ED, his nearest and dearest are distraught. Jan is in tears, Siobhan speechless, and frightened Faith hopes against hope that her deepest fears are not about to come true.

And finally, in the aftermath of the day’s dark events, Stevie makes a decision about her future at Holby ED…
