Warning: Spoilers for season 4 of The Umbrella Academy.

Summary

• Abigail accidentally destroyed her and Reginald’s home planet.
• Abigail’s actions led to an apocalyptic event called “The Purifying.”
• The main timeline has been restored and the Hargreeves erased from history, but questions about Reginald’s planet remain.

The Umbrella Academy Season 4 brought plenty of revelations and answers to the biggest questions from previous seasons, including what happened to Reginald’s (Colm Feore) home planet long before the events of season 1. The Umbrella Academy Season 3 ended with Reginald’s timeline becoming a reality and the Hargreeves and Lila (Ritu Arya) reuniting in it. The Hargreeves discovered they no longer had any powers, so Season 4 caught up with them six years later when they were all trying to live normal lives for the first time.

The Hargreeves teamed up once again for a rescue mission as they needed to find Jennifer (Victoria Sawal), but this forced them to team up with Reginald again as they needed some answers. Jennifer turned out to be the catalyst for “The Cleanse”, an apocalyptic event that was closely tied to the Hargreeves and Reginald through his wife Abigail (Liisa Repo-Martell). Abigail’s involvement in the end of the world also answered the question of what happened to her and Reginald’s planet.and that had a direct impact on her actions in Season 4.

Abigail Hargreeves accidentally destroyed her and Reginald’s home planet

Abigail was responsible for massive destruction

Abigail was the opposite of Reginald because she was kind and understanding, but she also had a big secret.

Abigail Hargreeves made her first appearance in a flashback in The Umbrella Academy Season 1, where she suffered while her and Reginald’s planet was destroyed. Reginald released the Marigolds before Abigail died and he left the planet, and Abigail was not seen again until Season 3. Reginald had kept Abigail’s frozen body in a capsule on the dark side of the moon, which explained why he sent Luther there on a mission for years. The machine in Hotel Oblivion not only allowed Reginald to reset the timeline, but he was also able to bring Abigail back to life.

Abigail explained to the Umbrellas that she had created the Marigold particle, but that she had also created an opposite particle called “Durango”.

One of the biggest surprises in Reginald’s Season 4 was Abigail’s presence, and so she finally made her official debut in The Umbrella Academy. Abigail was the opposite of Reginald because she was kind and understanding, but she also had a big secret. Abigail explained to the Umbrellas that she had created the Marigold particle, but in doing so, she had also created an opposite particle called “Durango.” When Durango came into contact with a marigold, it triggered an unstoppable physical reaction which led to the extinction of everything.

This was the event the Guardians called “The Cleansing,” and it would remove the broken timelines and repair the multiverse by restoring the main timeline. The big twist in The Umbrella Academy Season 4 was the Abigail was the one who made the cleansing possible by giving the Hargreeves the jar of marigolds so they could regain their powers, leading them to Jennifer, and making sure no one stopped the purification. Abigail explained to Reginald that she felt guilty for creating the Marigold and Durango particlesand their death was their punishment.

In this conversation The Umbrella Academy also confirmed that These particles destroyed Abigail and Reginald’s home planetwhich only increased her guilt. The provocation of the Purge was Abigail’s way of making things right, as she also felt she shouldn’t have been brought back to life. Reginald listened and understood her motives, and they were simply waiting to be devoured by the Ben/Jennifer Purge Monster.

What the Umbrella Academy previously revealed about Reginald’s home planet

The Umbrella Academy kept most of Reginald’s past secret

It is not known whether Reginald was the only survivor from his home planet.

Most of Reginald’s backstory in Netflix The Umbrella Academy is a mystery, but over the course of four seasons it has dropped a few clues. It is known that both Reginald and Abigail were aliens disguised as humans to blend in, though it is important to point out that they looked human even on their planet. It is unknown if Reginald was the sole survivor of his home planet, but prior to his customized timeline in Season 4, he was the only one of his kind on Earth.

Reginald brought a lot of knowledge and technologywith which he built his empire, contributed to the development of space technology and trained the Umbrella Academy. Thanks to The Umbrella Academy In season 4, it is now known that Abigail was also a scientist, so it could be that her species was highly intelligent, but unfortunately that led to their downfall. Thanks to the Purge, the multiverse was repaired and the main timeline was restored, erasing the Hargreeves from history.

However, this had no impact on the fate of Reginald and Abigail’s planet. Her home planet was nevertheless destroyed and Abigail diedbut it is believed that Reginald never released the Marigolds and that he may have died along with the rest of his people. The Umbrella Academy left many questions about Reginald and Abigail’s origins and home planet, but at least explained why and how it was destroyed.
