The Travelers, as any well-versed Trekkie would be happy to tell you, are a mysterious race of beings who first make themselves known to the Federation in the 2360s. Capable of tweaking space-time and warp fields purely through the power of their minds, Travelers can slip easily between both dimensions and time periods. Due to Travelers' ability to affect the very fabric of reality, upon becoming one of them, Wil Wheaton's Wesley Crusher gave up the prospect of interacting with his former family and friends.
Expanding on his reply to the Gizmodo query noted above, Wheaton said, "Wesley would like nothing more than to visit his mom, and meet his brother [Jack, played by Ed Speleers]." However, the "Star Trek: The Next Generation" star went on to explain that the Traveler rules that prevent any contact with figures from his previous existence are there for good reasons. And while being kept away from the most important people in his former life was clearly painful for Wesley, Wheaton said, "Not seeing them is a sacrifice he has to make in service of something so much bigger than anything else in his reality."
