Yup, what Pam and others have said. Also, you don't necessarily need level 10 fishing for deathfish - as long as you have a sim who can fish with live bait (I forget if that's level 5 or 7, but it's in the guide), you can catch some angelfish with alley catfish (which can be purchased from the grocery store), and then send them to the graveyard at night with the angelfish to get the deathfish. So, just keep that special opp slot open for one of her survivors, have a sim or 2 acquire a sudden interest in fishing and gardening (maybe even Cersei herself if the "oh my ghost!" opp appears sooner rather than later), and you'll get her back...if I'm reading this right, she'll be back as a vampire ghost, not human, but my understanding is that you can cure that for a couple thousand simoleons either at the hospital or the science center (not sure which). I don't know if vampirism can be cured before she eats ambrosia though, as my only foray into sim vampirism also ended tragically and I didn't continue with the file, but maybe someone else has experience with that.
