The hospital has now had to convert the cafeteria into a COVID unit, due to a surge in patients, and Koracick and Meredith are still very sick.
Unfortunately, patients who end up needing to be put on ventilators, especially early in the pandemic, do not have very positive prognoses.
Mer felt better for a bit, and even woke up enough to chat with Koracick, but she also took it upon herself (Stubborn Mer!) to get up and assist a patient when no one else was around, which led to her collapsing and Webber having to make the tough decision to put her on a ventilator.
