The Netflix series is one of the few that keep viewers continuously subscribing to the platform considering their recent antics.
The Umbrella Academy is by far one of the better Netflix Originals that the platform has been able to dish out as quality content.
With characters that are able to control death, time, and people, and put them into one big dysfunctional family, it is bound to be a source of great entertainment.
However, the series comes with its own set of setbacks.
Of course, when it comes to having powers such as time travel and resurrection, there are bound to be plot holes here and there.
Well, here we have some of the top plot holes which never got their explanation within the series:
The convenient time paradox
After the end of the first season, everyone was left bamboozled as to what happened next.
What are the consequences of escaping a world-ending threat by time-traveling into the 1960s?
Well, even though we got somewhat of an answer in season 2 of how everyone is dealing with the escape from Viktor's world-ending stunt.
It never really answered the question of how all of them are existing in such a time.
Due to the time travel shenanigans, the apocalypse that they had just escaped from caught up and set itself to happen in 1963 instead.
We all understood that the apocalypse changed its date due to Viktor time-traveling with the rest of the academy.
But, that does not explain they have managed to escape being wiped out of existence considering their births take place in 1989.
Meaning that they are existing in a time before their parents could even give birth.
Let alone the fact that their parents are dead due to the apocalypse being set in the period before they could even be born.
Time traveling or dimension hopping?
In a crucial sequence from The Seven Stages, episode eight of season two.
Tom Hopper's character, Luther, and his brother Five confront an older version of Five and attempt to take his time-traveling briefcase.
Although the show has kept viewers on their toes, some viewers have been perplexed by the absence of continuity in the encounters between the two Fives and time travel in general.
In the climactic episode of season two, Five uses his abilities to travel across time just seconds before Kate Walsh's character, the Handler, murders his siblings.
Yet, according to the rules that the show itself has created, time traveling creates another version of yourself from the original timeline as one travels back in time.
Meaning that there should be a Five that exists right before witnessing his siblings being murdered.
While watching as how another Five pops into existence.
Instead, Five remains a singular character without creating any alternate time versions of himself while time traveling.
This could only mean that Five just learned how to time travel properly and was hopping between different parallel dimensions with a similar timeline before this or the writers just forgot about the rule the show had created for itself.
Why does Grace exist in the Sparrow universe?
Reginald Hargreeves created a robot named Grace to act as the primary carer and adoptive mother for the seven children.
This concept was directly inspired by the comics, where the mother frequently mentions the need to put on her limbs before going out in public.
However, Netflix's The Umbrella Academy diverged from the comics in that season 1's destruction of The Umbrella Academy resulted in the death of the robot Grace.
Here is where things start to derail: season 2's revelation that the robot was based on a Grace Reginald Hargreeves knew in the 1960s changes the entire reason of her existence for her appearance in season 3.
As the original academy needed Grace to be created as Viktor constantly got rid of the human nannies with her powers.
The Sparrow Academy does not have a single member like him in that regard. Let alone, the fact that the Sparrow Academy has names at all.
Taking into consideration that is something that Grace from the original timeline did for the Umbrella Academy.
Another convenient time paradox
In order to return their family to 2019, Five and Luther require the older-appearing Five's briefcase.
Yet, due to paradox psychosis and their normal predisposition to resolve conflicts through violence, both Fives hatch a plan to murder the other.
Finally, teenage-looking Five opens the portal, and Luther kicks older-looking Five through it.
According to teenage-looking Five's theory, this should avoid a hypothetical paradox in which a different version of Five still visited the Academy in 2019 to halt that apocalypse, just as teenage-looking Five did in season one.
The Five in 1960s Dallas can continue to exist as long as a version of them does in that time period.
However, the version that they would be sent back into what is supposedly the original timeline would also have the knowledge of what is going to happen.
Unless Five knows how to erase or manipulate memories by sending himself into portals, the older-looking version of Five would already know that Viktor would be the cause behind the first apocalypse and could easily prevent the entire situation from derailing from the get-go.
