Even though most fans went totally gaga over the surprise appearance of Derek in Meredith’s dream sequence, it made them yearn for more of him on the show. It doesn’t look like the dreams will be a regular occurrence, because that might become overkill. But, showrunner Krista Vernoff told Deadline, it was meant to give viewers something positive amid everything else.
“From a writer’s perspective, it happened because it was my job to find a way — once we determined that we were doing the pandemic — to also bring joy, and escape, and fan candy, and all the things that at Grey’s Anatomy we give people,” Krista said. “We give them romance, and we give them humor, and we give them joy, and a lot of that is lacking for the medical community in this pandemic. And so, I was walking on the beach one day, and I was like, what if there’s a Meredith dream motif?”
