Showrunner Krista Vernoff tells Variety Karev's vanishing act “was a very careful threading of a needle, where we are giving a little bit of information and pain to Jo,” adding, “We’re, episode by episode, illuminating the story of where Alex is. And it takes us quite a few more episodes to get there and to give the audience clarity.”
