After that death in the season 22 premiere, Grey's Anatomy continued with someone revealing a surprise pregnancy - while another character chose to take a sabbatical. During the Thursday, October 16, episode of the hit ABC series, the employees at Grey Sloan Memorial Hospital were grieving Monica Beltran's (Natalie Morales) death with Amelia (Caterina Scorsone) taking it the worst. Meredith (Ellen Pompeo) was joined by Maggie (Kelly McCreary), who came back to help look after Amelia.
