In response to aGizmodoarticle on Picard’s unanswered questions, Wheaton shared “as close to an official answer” as we’ll get on why Wesley can’t pop in for a family reunion. Wesley became a “Traveler” in his final episode ofNext Gen, giving up his human existence to do so. He explained that while it’s not officially part ofStar Trekcanon, he used this explanation when he wrote “the Wesley Story for the 400thStar Trekcomic.”

According to Wheaton, “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.” He continued, saying that while “Wesley would like nothing more than to visit his mom, and meet his brother,” he knows that “not seeing them is a sacrifice he has to make in service of something so much bigger than anything else in his reality.“Wheaton’s appearance in thePicardSeason 2 finalefits within these parameters as he only appeared to extend an invitation to The Travelers to Kore Soong (Isa Briones).
