The Grey's Anatomy midseason premiere revealed whether Camilla Luddington's pregnant character, Jo, survived - or died - after having to deliver her babies early in a premature C-section. During the Thursday, January 8, episode of the hit ABC series, Jo remained unconscious after undergoing surgery to welcome her twins early amid heart issues. They were each put on ventilators in the NICU - with baby A thriving while baby B wasn't in the clear just yet. Link (Chris Carmack) watched over the newborns while also checking in on Jo, who wasn't getting any better.
