Who Killed Sara Season 3

It's pretty clear from the title — and the lack of a satisfactory conclusion of any kind in the previous season — that Season 3 is going to focus on the same thing as the first two: finding out who was responsible for killing Sara. Unless she's alive, of course. Who even knows, at this point. 

At the end of Season 2, fans were shocked when Marifer confessed to the murder by cutting Sara's parasail straps, but viewers later learn her act didn't actually result in the titular death even though she appears responsible for other killings. Of course, we don't know if Marifer survived the fire, anyway. By the end, it looked like Nicandro was going to be implicated instead, through a cryptic comment he made to Sara's psychiatrist on the phone. In other words, aargh.

Chema has confessed to murders he isn't guilty of, which doesn't bode well for his future. And Alex saved Elisa in the final episode, after her suicidal action in torching her family's casino. Elisa's been in some dangerous situations in previous episodes, so we're pulling for happier times for this couple when Season 3 finally debuts.
