As disaster episodes go, this one from season 11 is pretty forgettable. An earthquake shakes Seattle, but the hospital itself and the staff are left largely unaffected. The biggest storyline to come out of the earthquake itself involves Owen, Amelia, and Richard talking an 11-year-old girl named Ruby (a pre-Stranger Things Millie Bobby Brown) through a procedure over the phone, helping her treat a tension pneumothorax on her mother. However, as moving as Ruby's scenes are, they really don't have any significant impact on any of the main characters beyond this episode. The biggest revelation of the episode occurs when Meredith calls Derek, who is working in Washington DC, and a woman picks up his phone — but of course, that has nothing to do with the earthquake.
