Rebecca’s life gets more surreal when her investigations lead to another woman who looks exactly like her. Tamara is a stripper and the third triplet, and she knows about Aleida and then some.

Meanwhile, Captain Humberto Solana, who has been having an affair with Becca, continues to help her while his marriage with his pregnant wife gets progressively worse. He’s ultimately kicked out of home and begins staying with Becca, promising her to help with her case.

Tamara is enlisted by Eugenio to impersonate his late wife, in order to save their company from a hostile takeover. Becca continues searching for Tamara and eventually finds out what she’s up to. Meanwhile, Dr. Bátiz, who used to be Alieda’s shrink, volunteers to help Becca and Tamara out.

Becca finds some disturbing evidence that links her origins to some Nazi experiments. Later on, the social worker who handed her over to her adoptive parents gets murdered.

Becca becomes extremely cautious and entrusts Dr. Bátiz with the safety of her mother, while also looking for Tamara, who finally comes back from Eugenio’s captivity. Together with Humberto, the two sisters go to the safe house only to come across the biggest twist thus far.

The Triptych finale concludes with the villain going mask-off with their intentions, the triplets reuniting and defeating the antagonistic forces.

Triptych ending explained in detail:

What is Julia Bátiz’s experiment for?

Julia Bátiz worked alongside Dr. Meyer in the 60s. He was a renowned doctor who experimented exhaustively on twins and triplets. However, when the media got to what he was doing, he shut up shop and ceased all his experiments, burying years of work in the process.

Julia Bátiz didn’t want to stop so she moved to Mexico and eventually got put in charge of the psychiatric department at the Humanis Vita hospital by Dr. Bernardo Sáenz, who’d become her mentor later on.

With the resources and opportunities at her disposal, she’d go on to begin her experiments and her most crucial test subjects will end up being the triplets Aleida, Rebecca, and Tamara.

The three sisters are separated after a couple of months of living together after their birth. They were later adopted by families from three different socio-economic conditions.

Growing up, Bátiz would keep tabs on them continuously, even influencing their lives to the point that they all dated a psychologist one time during their lives. Meanwhile, she’d hire monitors who’d observe the sisters and influence them.

Humberto was one of these monitors, and according to Bátiz, her most effective one. Bátiz would also go to extreme lengths to keep the broader family dynamics the same for all the girls.

She’d go on to have Tamara’s mother and Rebecca’s father killed after having Federico Trujano, Aleida’s father, killed for catching on to the experiment so that all three would be deprived of one of their parents.

What was the purpose of the experiment?

Dr. Julia Bátiz is fascinated with the creator vs creation, the myths that deal with the concept. From Prometheus stealing fire from the gods to modern myths like Dr. Frankenstein’s Monster, Bátiz intends to answer a question.

What really matters in the confirmation of personality — nature or nurture? That’s the question she wishes to answer through her experiment, which is why she sends the triplets, three genetically identical people, to families with different socio-economic conditions.

Aleida ends up with upper-class adoptive parents, Rebecca with middle-class ones, and Tamara with poor parents. Growing up, Julia tracks their development and keeps a record of them.

As to how the nature part influences the girls to have a metaphysical connection with one another, it’s left as an ambiguous, inexplicable phenomenon that stands opposite of the tried and tested experiments of Dr. Julia Bátiz.

Who is the triplets’ biological mother?

It comes as quite a shock to Tamar and Rebecca during their captivity at the end of Triptych, when Dr. Julia Bátiz finally sheds the skin of her malicious person. She drops a couple of shockers on the siblings, from their origins to the purpose they were brought into existence.

Julia Bátiz wanted to experiment on them and required a set of extremely identical test subjects. That’s why she came up with triplets, who were all grown, as she reveals, in a petri dish.

The surrogate mother used to give birth to these engineered triplets in the experiment was none other than Dr. Julia Bátiz herself. This means that Aleida, Rebecca, and Tamara’s biological mother have been Dr. Julia Bátiz herself.

What happens to Aleida?

Like her father, Aleida would catch on to Dr. Julia Bátiz and her experiment. She then becomes aware of her sisters and begins investigating them. However, Dr. Julia Bátiz’s solution to Aleida is to trigger her psychosis and prove her mentally unwell.

She even succeeds to a great degree, but when Eugenio takes Aleida out of Julia’s care at his wife’s request, Aleida takes no time to take revenge as she goes to kill her.

However, Julia Bátiz manages to prolong her death, while having Aleida’s body swapped with another, a very similar body of a dead girl, even managing to fool Eugenio into thinking about his wife’s death when she was only in an induced catatonic state.

At the end of Triptych, Tamara, and Rebecca are shocked to learn that Aleida is still alive. Moments later, Aleida manages to escape her captivity and helps her sisters break out of their cells and fight the villains as well.

Triptych ends with the triplets fleeing their captivity, Aleida reuniting with Eugenio and her mother, and getting proper medical care.

What happens to Bátiz and Humberto?

Bátiz holds Aleida at gunpoint and there’s a brief standoff between her and the two other siblings. However, Triptych episode 8 shortly cuts to the triplets escaping the experiment facility.

Aleida meets Eugenio, and the sisters reunite with the mothers. Before the credits roll, it’s revealed that the sisters have trapped Dr. Julia Bátiz inside the basement of her facility. At the same time, the authorities fail to track her down.

Meanwhile, the show also reveals what happened to Humberto Solana. On their way to the facility where the triplets are to be experimented on — a location that Eugenio had gotten traced — Humberto takes the car off course.

Eugenio catches on to the suspicious change in course and when Solana’s pregnant wife calls him while in labor, Eugenio takes advantage of the distraction, and the ensuing struggle between the two men results in the car crashing violently.

While Eugenio survives the crash and goes to save the sisters, Humberto Solana is confirmed to have succumbed to the crash and died.
