Luc made his final appearance on the BBC medical drama this evening (January 8) as he vowed to go travelling, with hints that he was heading to India for a reunion with Eddi McKee (Sarah-Jane Potts).
Millson told Digital Spy today: "I enjoyed every moment of my time on Holby City. I believe it is a greatly underappreciated gem in the BBC's crown. Every single department excels, and at its best - tonight's 'Hanssen/Hemingway' episode for example - the writing and production are as good as ANY single dramas out there.
