Why it destroyed you: As Broods' quiet hymn fills the background, the doctors concoct an experimental, Hail-Mary effort to save their patient Karl. Per Dr. Webber's original request, they personalize Karl by thinking of people from their own lives. For Stephanie, it's her younger self, for Meredith, it's her children, and for Owen, it's his sister. It's a sentimental moment that reminds Grey's fans of their beloved characters' backstories and motivations.
