One rule of the evil bad guy (or girl in this case) spy handbook is to know when it worth the risk to expose yourself as a spy. If Cinder will have no more use for a spy, or at least thinks she won't, then there's no point in keeping that spy's cover. Let em loose to wreck havoc  and maybe collect them afterwards for their reward (in the villian side of things that often a bullet).
