The Good Son (TV series)

Raquel's death triggers a series of events that further pit the families against each other. Without Raquel's moral compass, particularly for her wayward son, Obet, the two boys are consumed with anger, cast adrift in an ocean of revenge, its currents controlled by a mentally ill Olivia. Grandfather Matias is helpless and his efforts to guide them is in vain. Joseph has an ugly physical confrontation with Olivia when she expresses her intention to return to BDG. Likewise, Obet continues on his trajectory towards his father's criminal path. Aside from purchasing a hand gun, Obet violently assaults Olivia outside her home. Things all come to a head when he threatens to push Matilda from the top of the hospital exit stairwell, leading to his arrest. Although the fiscal throws out the case for lack of probable cause, Arthur decides he has nothing to lose by revealing to the authorities his own bombshell: he colluded with Olivia to interfere with the investigation, that Olivia engaged his services not once but twice: first time was to lie about Raquel and implicate her in Victor's death which he refused, and the second time was to obtain evidence that she could use against Anthony in which he got paid. A pathological liar, Olivia admits to the meetings but quickly asserts that Arthur was extorting her.

Meanwhile, the Reyeses and the Buenavidezes receive threatening anonymous notes and suspect it is coming from Dado. Panicked over what Dado can divulge to all, Olivia searches for him. Still missing and without his medication, Calvin begins to lose touch with reality, his mind going back to the trauma of his father's death. He speaks of being wrongfully blamed for the poisoning, where in fact he claims there were two people who worked together to kill his father.

Tired of his mother's lies and the never ending hate, Enzo decides he will fight for the only thing he has: his father's legacy. Embarking on his own investigation, he starts in Anthony's home searching for any paper trail that would lead him to his uncle's last steps and shed light on what really happened to him, and why. Finding the truth and exposing it could permanently destroy his family or heal it.

Joseph, on the other hand, is close to unmasking the perpetrators. His idea to send anonymous notes to Olivia works. Panicked and fearful of exposure by Dado, she is followed by Joseph and leads him to Calvin. Calvin has a moment of clarity and discovers his dad's real killer. He contacts Justine to tell her he will warn his father of the killers’ plans. Justine alerts Enzo who rushes to Calvin's location ("at our dad's safe place") accompanied by Olivia but Calvin is fearful of them and runs away. Joseph, following Olivia, arrives to help but another altercation between Enzo and Joseph allows Calvin to slip away once more.

Joseph eventually finds Calvin and brings him into sanctuary in a convent. Determined to unnerve Olivia, he sends her another anonymous note claiming he has Calvin, further rattling Olivia who thinks it is Dado. Meanwhile, Olivia finds Villamanca and roughs him up who eventually gives her access to the funds which Anthony had instructed to transfer back to Victor's company for his three sons to inherit. Olivia prepares to retrieve the missing funds!

Believing she is at the home stretch, Olivia arranges to leave the country with her sons and mother as soon as she finds Calvin. Elsewhere at the ocean, fishermen find Dado's corpse, dead from gunshot wounds sustained from Arthur's attack.

Now suspecting that Joseph is sending the notes, Enzo and Obet follows him to the convent and a violent confrontation ensues culminating with a near tragic ending. Joseph saves Obet and Enzo from plunging to their deaths and the near death shakes them. The siblings realize their mistakes and iron out their differences, as they discover the awful truth about Olivia: in a recorded conversation between Olivia and Dado, the brothers hear her admitting she poisoned Victor and planned to hide behind Calvin's illness. Realizing that Olivia manipulated everything in her twisted and mentally ill mind, they decide to flush out their mother. Used to her expert manipulation to get away with murder, Enzo turns himself in as bait, an act that shakes Olivia's core, but does not admit anything. Despite Enzo's false confession to the authorities and risk to his future, Olivia continues to use legal due process while she surreptitiously arranges for new identification documents for her family to leave the country, which she plans to do as soon as she finds Calvin. Enzo has an intense conversation with his mother when he shows her the audio recording and begs her to make things right, but Olivia vehemently denies everything. Joseph decides to file charges against Enzo, both hoping Olivia will break when she sees her son in jail.

Enzo later visits his grandmother Matilda and tells her the reason why he confessed a lie, he thought his mother couldn't bear her son taking the rap for her crime and would owe up to the truth, but she didn't.

The Good Son premiered in Kenya on November 19, 2018, replacing the one-month run of Muling Buksan ang Puso on NTV during the 6pm pre-primetime slot. Its broadcast competes with the run of the Pangako Sa'Yo remake on rival network KTN Home.

The show was airing re-runs on Kapamilya Channel's Kapamilya Gold afternoon block on September 14, 2020, replacing Love Thy Woman and also on A2Z's Zuper Hapon on October 26, 2020. The teleserye ended on both networks on March 31, 2021, aside from April 2, 2021, due to Holy Week in the Philippines. It was replaced by re-runs of Magpahanggang Wakas.
