Isaac won't be killed of though, Davis comforted fans by stating "He specifically asked that we not kill off Isaac, so that he could have the chance to return. He said he loved the role so much that he wanted to be able to come back if there was a chance". So Isaac lovers, you may see your man again sometime in the future..
As to how Isaac will be leaving the show, Isaac and Argent (JR Bourne), "The story is going to be that Argent sort of takes a sabbatical in France to deal with the death of his daughter and Isaac goes with him, that's why you see them leaving out the door."
