Out of all the Tron ships, I think the Encom Trio cracks me up the most. Not because it’s improbable, but because it isn’t. Neither the original nor the sequel work that hard to dissuade from it. If snippets of the novelization have given me any impression, it doesn’t, either.
If you want to see Tron and Yori as more outgoing alter egos of Alan and Lora, it’s even funnier, because pre-Grid, although Kevin makes off-color jokes about him and Lora being together previously, and both her and Alan protest, they ultimately still find Kevin likeable.
And then in the grid, Yori’s reaction to accidentally being taught to kiss by Kevin is to show Tron. Not “that guy did something weird to me” but “hey, c'mere!” And we know programs were supposed to have a form of intimacy, enough to warrant revealing (ish) attire and getting a room ala the Users. They know what touch can mean and they seem to have preferences of who they do that with.
(Hell, I think the novelization literally has them saying “I love you.”)
Their roles aren’t that different from ours; it’s just that Yori learned a new form of circuit touching from someone she liked and shared it, acting as a kind of odd romantic conduit between this new guy and the one she’s already with. Tron, for his part, doesn’t seem near as annoyed with that as you’d expect.
If their actions are meant to be a reflection of the inner personalities of both of their Users, that’s pretty telling.
And then you get to Legacy, and oh lord, where to begin? Sure, there’s Jordan, for about a minute, long enough to establish Sam and a sense of family, then she’s gone because Dizknee mom plot, and Sam’s being raised by exactly who you’d expect him to be in Kevin’s absence. It almost makes you wonder if they would’ve just wrote him as a son of a poly relationship if they could’ve gotten away with it.
And Alan’s toting around that pager every day, waiting for a sign that his friend is still alive, not knowing that his own creation/possible reflection risked his life for and guarded said friend with all his might. We have no clue about Yori, but one can only assume she was just as loyal and involved up until a certain point.
It goes without saying how obsessive Kevin was, and is, about Tron. He can’t even keep Yori and Tron’s names separate from Alan and Lora’s. Clu is a bastardization of Kevin, and he keeps his lobotomized Tron as a prized slave fighter who rarely leaves his side. So, I mean, yeah. If you were going to come out of these films with any “non-canon” ship, I think that’d be the most obvious one.
