Over the course of its animated adaptation, Invincible has made several changes from the comics, including the races of its characters. However, the series has yet to deviate from any major events or when they take place in the timeline.
That changed in Season 4, Episode 6, "You Look Horrible," when Nolan informed Mark after he awoke from his coma that it had only been "almost two months." However, in the comics, Mark took much longer to recover, which means he'll return to Earth far sooner than expected.
The events of the Viltrumite War are far more condensed in the animated series than in the comics, which could affect multiple storylines moving forward, including Nolan's reconciliation with Debbie over what he did as Omni-Man.
Timeline of the Viltrumite War
How Long Was Mark Away From Earth?
While the Invincible comics don't spell everything out for the reader, they establish a few hard facts. When Mark reunited with Eve, whose powers had stopped acting up, he apologized for being away from Earth for "10 months" and that he "spent a lot of [the war] in a coma."
Fans won't know for sure until the end of Season 4 how long Mark has been away from Earth in the series, but so far, it appears his time off planet will be considerably shorter based on the facts so far.
How Long Was Mark's Recovery?
Unlike the series, the comics don't tell the reader how long Mark's recovery took, only that it lasted more than four months, at least according to Nolan's many conversations with Oliver about it.
In issue #73, shortly after Mark killed Conquest, Nolan estimated it would take "months" for him to recover. After "almost a month," Nolan told Oliver it "shouldn't be more than a few more months." So, already longer than Mark's "almost two months" long coma in the series. But another time skip between panels, and Nolan said Mark should fully recover, "in a month or so."
The "or so" does a lot of heavy lifting because, with more time skips established, thanks to Zack Thompson's Tech Jacket progressively growing beard. Nolan even told Oliver he's gotten stronger over the "last month."
So, in the comics, Mark's recovery took at least four months, but the time it takes to travel across space suggests he was in a coma for far longer.
How Long is Space Travel?
While it's unclear how long it would traditionally take to travel from Earth to Talescria, in issue #77, when Nolan and Mark are rushing back to Earth in "the fastest ship the Coalition has" from Talescria, he estimated it would take "a week or so." Nolan also mentioned that for the rest of the Coalition forces, it would take "longer than that."
However, according to General Telia in the series, it would take "two weeks" for them to reach Talescria from Earth. But keep in mind, they were hitching a ride on what this season has consistently shown to be a terribly unfit vessel. One that was no doubt slower than anything else in the Coalition fleet.
As for travel between other planets, in issue #75, after the Coalition finally discovered the mole, they all left Talescria for Viltrum, which took three days of space travel. For even further context on how quick space travel can be in the Invincible comics, in issue #25, the travel time between Earth and Thraxa is "six [...] days" using a Thraxan ship, which was the same time it took Mark to get there in the series.
Space travel shouldn't be a huge factor in the time Mark was away from Earth. At most, at least in the comics, the time traveling between Earth and Talescria shouldn't have taken more than two weeks, so collectively, a month's travel. Not to mention that three-day trip to Viltrum.
Final Verdict
The only other time Mark was indisposed or delayed was after he and his father were nearly killed by Thragg, following the destruction of the Viltrumite homeworld. According to Allen in issue #76, Mark was unconscious for "two weeks."
In the comics, for the timeline to make any sense, Mark had to have been in a coma for at most eight months. After all, there wasn't a moment when these characters stopped moving, and given how quick space travel is in both the comics and the series, it's the only way the timeline makes sense.
In contrast, Nolan explicitly told Mark that he had only been unconscious for "almost two months," drastically shortening his time away from Earth. Unless the time it takes to travel to Viltrum or Mark's recovery after fighting Thragg is made significantly longer in the next two episodes, Mark will have only been away from Earth for four months by the end of this season.
Six months sooner than the comics, which could affect multiple storylines on Earth that depend on the biggest time jump the series has had since Season 3.
How Could This Affect Omni-Man's Relationship with Debbie?
The biggest thing that happened in the comics while Mark and Nolan were away from Earth for 10 months was that Debbie broke up with Paul off-panel. The first time readers see her again in issue #78, she's calling Paul to pick up his things from the house, harshly telling him, "I don't want any of this crap. I don't want to look at it."
As for why exactly she broke up with him, the only reason given was that "things with Paul just...felt wrong" after she saw Nolan again. He didn't even know Debbie was dating Paul until this moment, with him smugly saying, "And yet after seeing me, you could no longer stand to be with another man." Something that Nolan from the animated series would never say.
Looking back at their abrupt reconciliation, there's no doubt that the series will drastically change how these two will get back together. For one, it's unlikely that Debbie would just break up with Paul off-screen, especially after only four months, and how much more characterization Paul has been given compared to the comics.
It wouldn't be surprising if, to establish the four-month time jump, she's already moved in with Paul in their new house after selling her old one. Perhaps with these extra six months, the series could more naturally lead to Nolan and Debbie getting back together, while continuing to develop his road to true redemption.
