"Shaken, not stirred."
yeah but you have to remember, writing the death of someone into a script believably is hard enough as is, let alone doing it on a time limit. if the actor has other things to do, they cant always hang around to see the death out. recasting makes it easier for everyone. as the producers put it - if you're a fan of the show, and not of the actors, then you will adjust.
