Dr Dominic Copeland gets a shock when new registrar Isaac Mayfield arrives on Keller this week. It seems they already know each other – and that’s because Dom and Isaac recently had a one-night stand! Issac’s amused by the situation, but Dom is reluctant to work with Isaac to treat patient, Ade, found collapsed with stomach pains.

And Dom certainly doesn’t appreciate it when Isaac dismisses his idea of performing a routine splenectomy on Ade, suggesting a ‘cutting-edge’ procedure instead. Later, though, it seems Dom’s warmed to having Isaac around. Has unlucky-in-love Dom finally found his Mr Right?
