and causing Ric to form a mutiny with fellow members of staff, Hanssen offers to operate on Ric in a risky bid to remove his terminal cancer. Henrik's friendship with Sahira Shah (Laila Rouass), who he hires to Darwin Ward in early 2011, is frowned upon by many of his colleagues, who believe that he is favouring her. Sahira is able to make Hanssen see the error of his ways several times and seems to calm him. Her relationship with Greg Douglas (Edward MacLiam), another Darwin surgeon, leads to conflict between the pair, and the belief that Hanssen has feelings for Sahira. When the affair between Sahira and Greg comes out, Sahira leaves the hospital, and it is revealed Hanssen feels like Sahira is a daughter to him and is distraught by her departure.

Hanssen then finds out that Elizabet wanted Anders to use the data so that her brother's death in the Holocaust wouldn't be pointless, and that the true reason she committed suicide was because she thought Anders was dead after his disappearance and she couldn't live without him. Now knowing the truth, Hanssen forgives his father and reunites with Anders on his deathbed. Hanssen agrees to return to Holby, to Serena's anguish, and quiets the board by making Serena his deputy. Hanssen becomes close to F1 Tara Lo (Jing Lusi) when he discovers she is practising with a brain tumour, he warns her that if any
