You'd think we'd have learned not to get too attached to characters who are also patients, but Henry managed to break our hearts nonetheless. Henry is first introduced as a chronic patient with a condition that makes him grow tumors. When Teddy Altman finds out he needs insurance, she impulsively offers to marry him so that he can use hers. It starts out as a marriage on paper only, then develops into a close friendship and eventually a real romance. That's what makes it all the more heartbreaking when, just as they start to plan a long-term future, Henry is rushed into the OR with what turns out to be an inescapably fatal condition — and Cristina has to operate, not knowing who he is until after he dies.
