Station 19‘s Maya actor Danielle Savre has commented on a potential franchise return in Grey’s Anatomy, explaining the possibility of coming back. Station 19‘s series finale offered bookends to many character story arcs, including Maya Bishop, a Captain on the team whose wife is Dr. Carina DeLuca (Stefania Spampinato). Carina is an OB/GYN Attending at Grey Sloan Memorial Hospital, one of many connective elements between the two shows. While neither character has appeared since their spinoff ended, the possibility remains open that either of them could show up in the ongoing medical series.
