I agree about using "Celia". Typing Celia-Cristal became a pain after a while. I couldn't even do "CC" for obvious reasons, and "Criselia" was kind of bizarre.
You can often glean some of the behind-the-scenes issues from how producers treat the "departed" on soaps. If they kill off a character and then sanctify their memory, it's usually a sign they didn't want the actor to leave. If the characters forget the character ever existed five minutes after it is gone, it's usually a sign the writers were miffed that the actor left, but if they go out of their way to assassinate the character, post-mortem (that is, undo all the good things the character did, or spend time turning the audience against the character in its absence) then you can be sure someone BTS was very pissed.
Now that Blake has returned from his trip (ostensibly the tour of the "shit-hole countries" that Celia had suggested Blake make in order to help rebuild Carrington-Atlantic's reputation), he might deal with Celia's will/estate. There's nothing quite like opening probate to bring everyone running. And of course Cristal Jennings will see her credit report suddenly blow up like a C-A windmill.
