If Robin is killed off (as rumors would suggest), he would still be credited in the remainder of episodes. He is main cast, and on contract. And just killing his character on the show would not break the contract.

Go back to Season 3, and you'll find that MRJ was credited in all episodes after Quiet Minds, even though he only appeared in "A Curious Thing" and "There's No Place like Home".
