A few months ago I theorized that Nelle could get herself murdered in the midst of a Wiley kidnapping attempt, and I stand by my dream plotline. Most of the key suspects are still in place, too:
Michael
Carly (if only)
Willow
Julian
Lucas
Sasha
Chase
Harmony*
Valentin
Nina
* I include Harmony only because she is such a tertiary character at this point, and she could reveal that her motive was to steal back the necklace. Nelle has it, but only because she stole it from Willow that night Nelle knocked Willow unconscious. Harmony does not want the whole story of how she ended up with Willow to come out, so she killed Nelle to get the necklace back. This is obviously because I don't want Nelle to be Nina's real daughter.
I had to remove Brad from the suspect list since he appears to be staying in jail for good. In his place, we now have (Tad) Martin Gray.
I think I have come up with a convenient way to undo Valentin's takeover of ELQ. Oscar's shares. The court case surrounding who actually owns them was never really resolved. Nelle claimed she inherited them, while the probate court was deciding whether they were in trust for that charity Oscar wanted set up (sending kids to climb mountains in Africa or something). I believe Nelle gave Valentin her proxy as if she owned them, but if the court says she has no ownership then Val no longer has the majority of voting shares and a new vote has to be called. Of course, even if she emerges victorious, it might be short-lived victory--if Nelle DIES then Oscar's shares go to...Wiley, who is in Michael's custody.
