Sam Nicholls

Samantha "Sam" Kent (née Nicholls) is a doctor and former registrar at Holby City ED. She started working at the ED in October 2011. She became romantically involved with Tom, when the couple ended up kissing after a night out in the pub. They married in December 2013, before leaving the ED together to start fresh.

Time in the Emergency Department (2011-2013)
Over time, their relationship grows closer, and Tom announces that he wants a committed relationship with her after he gets jealous when another doctor asks her out. A speech exclaiming his feelings towards her and a kiss in the middle of the E.D convinces her that she really loves him. Tom then struggled through a drug addiction due to panic attacks, but Sam helped him through it and he promised to stop taking the drugs. After a short row where Tom hit Sam by accident, Sam forgave him and the two made up, leaving the series 27 finale with a kiss. The couple have returned to their 'happy-in-love' stage, and their relationship grows ever closer. In series 28, Tom decides he wants to propose to Sam but his proposal plan was ruined by Robyn and Iain. Sam hastily proposes to Tom herself, to which he accepts. Sam and Tom marry and leave Holby together for an 'extended honeymoon' and fresh start.
