Mr McDerrick is the consultant who oversaw the treatment of Tricia Dingle after she gravely injured in the storm. He summoned Tricia's husband Marlon to his office, where he broke the news to Marlon that Tricia is only being kept alive by machines. 

He informed Tricia's family that Marlon will have to decide to switch off her life support machine within 48 hours or they'll take the decision regardless. Ultimately, Marlon decided it was for the best when he finally realised that Tricia may never wake up.
