Warning: spoilers for The Umbrella Academy season 4.
Summary
The Umbrella Academyseason 4 answered the biggest questions left by past seasons but left many others unanswered, and thanks to one big reveal, I think I now knowwhy the Sparrow Academy’s Christopher was a cube. After three seasons of time-traveling, chaos, drama, and many twists,The Umbrella Academyended with its fourth season. The final episodes were packed with shocking reveals and an ending that’s equal parts heartbreaking and hopeful, and some of those necessary reveals might have answered a big mystery for me.
The Umbrella Academyseason 4 caught up with the Hargreeves and Lila (Ritu Arya) six years after season 3, revealing that they had all been living normal lives for the first time. The team was brought back together for a rescue mission, but this task came with unexpected turns. The team had to reunite with Reginald (Colm Feore) as they needed answers, and thanks to him, they regained their memories about the death of Umbrella Ben (Justin H. Min) and Abigail (Liisa Repo-Martell) explained the new apocalypse to them – and thanks to that, I think I know why Christopher was a cube.

The Umbrella Academy Season 4 Ending Explained
The Umbrella Academy has ended with its fourth season, which saw the final apocalypse and some shocking reveals that changed the team’s lives.
The Umbrella Academy Doesn’t Show The Sparrow Timeline’s Jennifer Incident
The “Jennifer Incident” Wasn’t Exclusive To The First Timeline
InThe Umbrella Academyseason 3, the Umbrellas mentioned the “Jennifer incident” for the first time. This referred to the death of Umbrella Ben when they were 16 years old, but the details behind it weren’t revealed until season 4. All that was known was that Ben died while on a mission with his siblings and that the latter had failed as a team. Season 4 Reginald helped Allison (Emmy Raver-Lampman), Viktor (Elliot Page), Luther (Tom Hopper), and Diego (David Castañeda) regain their memories of Ben’s death, revealing that Reginald killed his own son and a young Jennifer.
The young Umbrellas were on a mission to destroy a container that kept a dangerous weapon but were instructed by Reginald not to look inside it. Ben heard Jennifer inside the container and took her out of it, touching hands and thus activating the marigold/durango reaction that would have triggered the end of the world.Reginald suddenly appeared and shot Ben and Jennifer in the head, killing them on the spot, and later messed with the team’s memories so they wouldn’t remember he killed them.

All members of the Sparrow Academy were alive, but it was revealed that this timeline had its own “Jennifer incident”.
The Umbrella Academyseason 3 saw the Umbrellas and Lila in a different timeline where Reginald’s team was the Sparrow Academy, and their Number 2 was none other than Ben.All members of the Sparrow Academywere alive, but it was revealed that this timeline had its own “Jennifer incident”. Ben had various sketches of Jennifer in his room butthe details about their “Jennifer incident” weren’t revealed, and I have a feeling it wasn’t Ben who was involved in it: it was Christopher.

Christopher Becoming A Cube Might’ve Happened Because Of Jennifer
Christopher’s unique physiology and the mystery around the “Jennifer incident” in the Sparrow timeline make me believe that he was the one who came into contact with Jennifer, not Ben.
The Sparrow Academy’s Number 7 was Christopher, a telekinetic cube of unknown origin but who was adopted by Reginald like the rest of the team, as he was one of the 43 superpowered children, somehow. Christopher could create sounds that his siblings understood and emitted a light that seemed to be linked to his emotional state.Christopher’s powers were electricity generation, inducing cold by manipulating the temperature of the room, inducing fear into others’ minds, and paralyzing them with fear.

Christopher might have been a normal, human boy when they met Jennifer, and he was the marigold host that Jennifer’s durango needed.
In season 3,Christopher was used to contain the Kugelblitz, but this was only temporary as he later exploded and re-released the Kugelblitz, killing him and his sister, Fei. This, his unique physiology, and the mystery around the “Jennifer incident” in the Sparrow timeline make me believe that he was the one who came into contact with Jennifer, not Ben. Season 4 showed what happened to Ben when he touched Jennifer, so Christopher might have been a normal, human boy when they met Jennifer, and he was the marigold host that Jennifer’s durango needed.
However, Sparrow Reginald had a very different way of dealing with this than the original Reginald.I’m thinking that Sparrow Reginald, instead of killing Christopher, found a way to contain the reactionof the marigold/durango interaction andthat’s why Christopher was now a cube. The reason why this Reginald didn’t kill his son was because he desperately needed seven superpowered children to power the Oblivion machine, so he had to save him at all costs, even if that meant turning him into a strange cube.
Christopher’s Origin Is One Of The Umbrella Academy’s Biggest Mysteries
The Umbrella Academy Left Various Mysteries
Season 4 had no reason to explain why Christopher was a cube, and season 3 didn’t have time to do so, either.
AlthoughThe Umbrella Academysolved many of the show’s biggest mysteries, it also left many others that won’t be solved now. Among them is Christopher’s origin, which the show never bothered to address. As Christopher died inThe Umbrella Academyseason 3 along with most of his siblings and season 4 took place in a completely different timeline, there was no reason to explain why Christopher was a cube, and season 3 didn’t have time to do so, either.
Christopher being the one who had the “Jennifer incident” in the Sparrow Academy seems the best explanation to me about why he was a cube, why Ben was still alive, and why he knew Jennifer existed, more so as there’s no wayThe Umbrella Academycan solve this mystery now.
