is izzie EVER coming back to greys anatomy? یا is she definately gone for good?

She is gone for good. Katherine Heigl, the actress who played Izzie, opted out last season and decided not to come back. Thus, her contract was not renewed!

She's gone for good. Shonda Rimes has کہا that Alex won't be getting any closure about his relationship with Izzie until nest season. Katherine Heigl is not returning because she wanted to leave the show.
