Well, first of all I'd go with your instinct that you shouldn't be the one to notify the editors. Regardless of whose "place" it is, it's just generally not a good idea for a third party to break news like that.
And as for the liver transplant...anyone who knows more about this,
please jump all over me, but I've always been under the impression that a person sick enough to require a transplant would be quite sick, certainly too sick to turn up for work on a daily basis.
Sounds like your best bet is just to sit back and watch the show, really.
