Meredith struggles to treat the patient while navigating her grief, despite opposition from Richard Webber (James Pickens Jr.). At the same time, Cristina Yang (Sandra Oh) faces the sudden death of her mentor, Craig Thomas (William Daniels), during surgery.

Upon its initial airing, "Beautiful Doom" was watched by 9.26 million viewers and earned a 3.3/8 Nielsen rating in the 18–49 demographic, making it the highest-rated television drama of the week. The episode received positive reviews from television critics, with praise directed towards Pompeo and Oh's performances.

The episode opens with a voice-over narration from Meredith Grey (Ellen Pompeo), reflecting on the frustration of life's uncontrollable moments and the helplessness that comes with them.

Meredith is forced to juggle parenting with work when Derek Shepherd (Patrick Dempsey) is away for a lecture in Boston. While on the phone with Cristina Yang (Sandra Oh), who is bragging about an aneurysm case, Meredith drives past a serious car accident. She pulls over to help and finds a woman trapped under the car, triggering memories of her late half-sister, Lexie Grey (Chyler Leigh), who was trapped in the plane crash. Throughout the episode, Meredith and Cristina lean on each other, maintaining their long-distance friendship as they cope with their respective hospital responsibilities and the trauma of the plane crash.

Cristina and Dr. Craig Thomas (William Daniels) consult with a patient who needs two surgeries to repair an aneurysm and its underlying defect. The patient and her husband turn out to be doomsday preppers, adding an unusual dynamic to the situation. Meanwhile, Meredith becomes determined to save her patient, Melissa, but her emotional investment, likely influenced by her memories of Lexie, concerns Richard Webber (James Pickens Jr.), who questions whether her judgment is clouded. Despite his concerns, Meredith pushes forward, though she eventually agrees to pause the surgery when Richard insists.

At the same time, Cristina worries about her patient and the consequences Dr. Thomas might face for performing the surgery. While Cristina supports Dr. Thomas, he suffers a heart attack mid-surgery, forcing her to complete the operation on her own. Afterward, Cristina informs the patient's family that the surgery was successful, despite the tragic loss of her mentor.

Meredith, after completing her surgery, enjoys a brief moment of levity with her team by initiating a 30-second dance party. Later, she panics when she can't find her daughter Zola but eventually finds her with Owen Hunt (Kevin McKidd), who had been watching her while April Kepner (Sarah Drew) was in surgery.

Cristina calls Meredith again, sharing her concerns about Dr. Thomas and his impending firing. Meredith advises her as she faces her own concerns about her patient, eventually deciding it's the right time to operate again. In the end, Cristina arrives at Meredith's house, where the two friends share a quiet moment reflecting on their shared grief. As Cristina says, "Everyone's dead," they hug, finding comfort in their enduring friendship.

The episode was written by Jeannine Renshaw and directed by Stephen Cragg. The episode prominently features crossovers between Seattle, with Meredith Grey (Ellen Pompeo) at Seattle Grace, and Minnesota, where Cristina Yang (Sandra Oh) was practicing at the Mayo Clinic. These crossovers were depicted using split-screen sequences.

William Daniels makes his final appearance in the series as Dr. Craig Thomas.
