Rorke gets Hanahaki disease except he specifically starts coughing up Angel's Trumpets (same flower they use to make scopolamine cause of Devil's Breath) and it onsets after the brainwashing's successful and he's lost faith in Elias. Which makes him incredibly confused cause at that point, who the hell would he even love to cause this?
He keeps it a secret because he hates thinking about the implication of it. But then it gets to the plane scene and Elias has him pinned and halfway through his taunting, he's cut off because he starts coughing the blooms up, much to his utter horror.
