Casualty: Crystal Yu makes her debut as spiky new junior doctor Lily Chao – preview pictures

Ash is charged with mentoring the new arrival but finds her bedside manner leaves a lot to be desired

Casualty is to get a spiky new junior doctor in the form of Lily Chao, played by Crystal Yu, who will make her debut in the episode airing on Saturday 3 August.


Upon her arrival in the emergency department, the focused and intellectually fierce Lily is teamed with Ash (Patrick Robinson) as her mentor and is thrown in feet first when she tries to uncover the link between three apparently unconnected patients.

However, Lily does manage to spend her first shift annoying everyone she comes across (except receptionist Louise, who appreciates a strong woman!) and in the end it’s left to Ash to give her a warning about her bedside manner.


Crystal Yu, whose previous screen credits include CBBC series Spirit Warriors and Sky1’s Dream Team, said of her new role: “It’s such a privilege to be joining the cast of BBC One’s Casualty.  I’ve learnt so much from my amazingly talented fellow cast mates already.  I am really enjoying all of the medical jargon and being taught the various techniques – I now know how to suture!  I’m definitely beginning to find my inner geek.”
