That's the only way I'll accept Ward coming back and I sort of expect them to do this now that you mention it. Ward stays dead, actor can still be on the show. Lincoln stays dead, no one makes a LMD of him because who the fuck cares? Everyone is happy.
What would be the point? Everyone hates Ward, and no one would want a robot that thinks and acts like Ward. Maybe a Ward LMD inhabited by the pure energy form of Lincoln?
