This is, obviously, the final appearance by Wil Wheaton as an opening-credits regular, as the actor wanted the freedom to pursue other roles (ones which wouldn’t result in fans wanting his character to die, no doubt). He’ll be back as a guest star in “The Game,” “The First Duty,” “Parallels,” and “Journey’s End,” as well as a cameo in Star Trek Nemesis. And currently, you can see him in recurring roles on no fewer than four shows: Leverage as the obnoxious hacker Ka0s, The Guild as obnoxious gamer Fawkes, Eureka as the obnoxious scientist Dr. Parrish, and The Big Bang Theory as an obnoxious version of himself. (Hm, there seems to be a theme here...)
