Sammy T. Dobson on the complexity of her Casualty doctor’s uncharacteristic behaviour and painful past…
Sammy T. Dobson has been a Casualty fan-favourite since joining the BBC medical drama as warm-hearted and empathetic doctor Nicole Piper in 2024. So, naturally, viewers were stunned when she unceremoniously dumped her partner, nurse Ngozi Okoye (played by Adesuwa Oni), without explanation before the commencement of the current 12-part miniseries Supply and Demand.
Since then, we’ve learned a lot more about Nicole’s troubled past and the hidden reasons for her recent behaviour. While on a recent visit to the show’s fantastic set in Cardiff, What To Watch and other press caught up with Sammy to learn more about Nicole’s emotionally charged storyline, which escalates when this week’s episode airs on Saturday 23 August…
