So I've had conversations about this last part.
And I've encountered the argument that the wording here shows carelessness... or lack of understanding of the material... or perhaps just Disney seizing a chance to use one of the movie's catchphrases, to make sure it sticks in the audience's head for maximum marketability.
(which I have seen Disney do... at least that's often my assumption about scenes in Disney movies, where an iconic or potentially-iconic phrase is used that... really doesn't fit the context)
And I'm not necessarily gonna argue that this was anything more cerebral or more noble than that, on the Doylist level.
But. Hey. You know the Doylist level is not where I hang out anyway. Where's the fun in that.
The issue here, is that Dumont addresses Tron and Yori as "video warriors."
The complaint I have seen, is that neither of them exactly fit that description.
Tron comes close-- he is definitely designed to be a "warrior," to fight threats to the computer system, in his function as a security monitor. But he was not intended to be involved with video at all.
His only connection with the "video" aspect of things, is the implication that some of the battles Sark forced him to fight were echoed on the User side of the screen, in the form of video games.
Tron could, in that sense, be called a video warrior. But I really doubt he'd like being identified with that. It'd be like calling him a slave or a prisoner-of-war. A true statement, about his past... but why bring it up like that, out of nowhere, when talking hopefully about the future?
Yori, meanwhile, is not a warrior at all. At least in the sense of physical combat. She makes the plans, she's the machinery expert-- Tron goes to her for everything in his mission except the fighting.
But her function, from what we see, has a lot more to do with "video" than his. She's shown to be part of the laser computer, rendering User-world matter into digital form. That is, translating objects from User-world physics into versions that can fit in her world--into digital visual animations, which, in a sense, are very much like videos to represent the real things.
And when the MCP takes her away from that function, and makes her work for him, she is shown working on the Solar Sailer Simulation. Which is (at least in scripts and supplemental materials) suggested to be a User-designed simulation, something the Users can view on screen, for reasons of their own. Again, she's working with something that, to a User, is a sort of video.
And this does seem to be a passion for her, even outside work. The Deleted Love Scene shows that she even uses her visual simulation skills for leisure activities: for creative home decorating and fashion.
And, to be fair... she also does use these skills, in many ways, to help Tron and the rest of the User-believers win the rebellion.
And it's arguably important to acknowledge that.
For better or worse (whether or not you consider a specific war, or any war, to be worth fighting)... it's often important to point out that people who are involved in a war, working toward the victory of their side, even if they're away from active combat, are still in the war.
So, in a sense, Yori, too, could be called (but might not like being called) a video warrior.
If you want to theorize a valid reason why Dumont used those words-- a reason in keeping with who he was, what he believed in, and the amiable relationship he had with both Tron and Yori--
then, you might argue that he called them both "video warriors" as a sort of tribute to what they went through.
A closing line to this sad chapter of their lives, just as the new, happier one opens.
To acknowledge Tron's and Yori's part in winning this war-- as well as the specific kinds of work they both had to do, in order to accomplish that.
Work they probably don't like being reminded of.
But I like to imagine that Dumont-- in his own strange, spiritual, philosophical way of thinking-- was deliberately establishing the last time they would ever have to be called that. And making sure that last time was an acknowledgement of their victory.
Right before changing the subject to a brighter one: "Every tower is lighting up."
