In response to
an io9 article about questions left unanswered by the
Picard finale, Wheaton wrote on
Facebook, “One of the fundamental rules of being in the Travelers is that, once you’ve joined, you must NEVER interact directly with the people, places, planets, etc. that were part of your previous life, because it can affect your judgment and break reality.” So while “Wesley would like nothing more than to visit his mom, and meet his brother,” he’s willing to make the sacrifice because he’s “in service of something so much bigger than anything else in his reality.”
Wheaton admits that his explanation is “headcanon,” deriving largely from a story he wrote for
Star Trek #400, a celebratory anthology comic from
IDW Publishing, specifically the story, “A Matter of Choice,” drawn by Joe Eisma, colored by DC Alonso, and lettered by Nathan Widick.
But rather than explain Wesley’s situation, Wheaton’s story actually further
complicates it. The fact that Wesley is present for the wedding of Deanna Troi and Will Riker in
Nemesis, and that he did appear in the finale of
Picard season two to recruit Kore Soong to the Travelers (technically, an alternate reality, we guess, but it’s still a timeline touched by Jean-Luc), proves that the rules can be broken. And no sooner does Wesley tell readers about his restrictions than he visits an elderly Picard in that very same comic book, before going on to find Kore.
Ultimately,
Wheaton’s explanation is not canon and thus doesn’t entirely have to gel with the shows and movies. In my headcanon, Wesley was there in Ten Forward during the poker game, standing by off-screen Guinan. But every time he tried to speak,
Picard responded in his usual way.
