It was really a ONS. Lucinda explained that they knew each other before they had met her. Later she explained to John that they sought comfort in each other's arms because of grief.
Personally, I think they worked much better as antagonists, that's where the heat came from. Marland was smart not to revisit this, imo. Today's soaps show no such restraint and continue to beat old story threads to death. A mistake.
The only issue is her Southern accent afaic, There are people who look just Sierra in any Central and Latin America with the influx of Germans in the post WWII period (ahem, we all know why) and their German descendants stayed. Telenovelas are full to the brim with actors/characters who look like Finn and they were born and raised in countries like Mexico, Argentina and Perú and their roots are nowhere near the Iberian peninsula, lol.
Finn returned in 94 after Marland's death, and the entire show seemed funereal at that time.
When did she return before that? I thought her only previous return was in '89 when she helped usher Scott off the canvas, when he wanted to leave again.
Boynton's casting wouldn't fly either with that quasi-"Scarface" accent. The only person who would be allowed to stay would be Karina Arroyave.
Uh, when was Sierra ever in a triangle with Emily and Tonio??
