performance delivered one of the truly great Holby characters.” Henry did an interview with Digital Spy, discussing his final episode on 7 October (the day before his exit scenes aired). Speaking of his final episode, Henry said: "As usual, what he [Hanssen] does is go into mega-vicious mode. But he does also face a challenge, because he has to do a type of surgery which he hasn't done since he was a junior doctor years and years ago. This frightens him and challenges him.

Henry said highlights of his time at Holby City was the storyline with Dylan, in his first episodes, working with Laila Rouass (Sahira Shah), Paul Bradley (Elliot Hope), James Anderson (Oliver Valentine) and Jimmy Akingbola (Antoine Malick). Henry also revealed that when he renewed his contract in 2012, he told the producers that he would not be renewing his contract after that. Throughout the interview, Henry spoke very highly about how pleased he was with his final episode. When asked whether he may return in future, Henry said, "Who knows?".

His return was announced alongside those of Oliver Valentine (James Anderson) and Essie Harrison (Kaye Wragg). Kilkelly said Henrik would cause "waves" upon his return, after deciding to bring his "surgical brilliance" back to Holby. Henry expressed his gratitude at being able to bring Hanssen back, saying "He's such a weird and wonderful character to play - I've missed him! And the cast and crew at Holby are such fun to work with - I've missed them too. We don't know what dark acts may have befallen Henrik during his time away in Sweden but I do believe that, when he looms down the corridors of Holby once more, his wit and his scalpel will be as incisive as ever!" Executive producer Oliver Kent commented on how the news should "excite Holby fans old and new" and he was "delighted to welcome back Hanssen, Oliver and Essie as they were popular with viewers. Henry began filming in January 2015. When Guy Self (John Michie) stepped down as CEO to head up a neurology centre, Serena contacted Hanssen about taking over the vacant position.
