By the end of Triptych Season 1 Episode 8 we learn that the siblings were part of a twisted experiment which is why they had different upbringings and were seperated. It’s ending that brings many questions. The final episode also reveals the real biological mother and the burning question of whether Aleida is alive or dead.

The plot is kick-started by Rebecca discovering the body of Aleida, a woman who looks exactly like her. Despite having been shot, Aleida is alive and refers to Rebecca by her name, which understandably piques Rebecca’s interest.

Aleida has taken Dr. Julia Batiz hostage and was adamant about her revealing the truth, putting a few innocent people at risk in the process.

Rebecca and Aleida have a lot in common. Rebecca struggles with alcohol and is dating a married man, Humberto, who just so happens to be in charge of investigating Aleida’s case. What might cause a woman to sacrifice a very good career to enact violent revenge?

Well, that’s the question that drives Rebecca, who learns through a DNA test that Aleida is her identical twin, and from her mother that she was adopted illegally. Aleida passes away, but there’s a third sister, Tamara, a dancer who was also known to Aleida. After going through Aleida’s things, she’s led to the club where Tamara works.

Why were the siblings separated?

Towards the end of Triptych, we come to learn that the siblings were separated as part of a cruel experiment by Dr. Batiz, who wanted to understand the minds of triplets and how ostensibly identical siblings could nonetheless be shaped by their environment and circumstances. This is why the sisters had such radically different socioeconomic upbringings. It was a nature versus nurture study.

Naturally, when Rebecca and Tamara gradually find out more and more details about this inhumane endeavor, they want to expose it, but Dr. Batiz has them kidnapped and locked up in glass cells.

Batiz only ever saw the women as subjects, and she interfered in their lives very cruelly, worsening Rebecca’s alcoholism and pushing them to near-madness.

Who is the biological mother of Rebecca, Aleida, and Tamara?

While explaining the nature of her experiment Dr. Batiz also reveals that she is the biological mother of all three siblings. However, as described above, she has no love for the siblings and has experimented on them their entire lives.

Is Aleida alive or dead?

Batiz also reveals that Aleida is alive and has been kept in a room in the same mansion the whole time. The sisters are able to rescue her and escape, leaving Dr. Batiz behind in the same spot, where she will probably never be found.
