It's the only way any peace will return to the Del Junco family and everyone around them. Both are mentally ill and irredeemably evil. If I were the writers of the soap, I'd have them both killed in a fiery car crash, it seems the only logical solution to wrap things up fairly and neatly.
shareI won't be disappointed if Cayetana is killed in a fiery car crash. Although I see her eventually discovering that Emilio and Leonardo were the true causes of many of her family's problems, then feeling like a dumbass for putting too much of the blame on the Gallardos -- whose problems also started with Emilio and Leonardo and they don't realize it, yet. Cayetana may be considered a redeemable character (by the writers) since we saw her do the right thing by going to the Captain and telling him what she knew about Isadora and Arturo. Maybe she'll shoot Leonardo...
Mag, Darling, you're being a bore.
