Returning to the OP... I wouldn't call Tuvok selfish for behaving this way. He is just not very gregarious and does not like spending his free time with the rest of the crew. And I can't say I blame him--I wouldn't want to socialize with Paris, Kim, or Neelix myself. In fact I would probably avoid them, just like Tuvok does. Just like Worf, come to think of it. Do you think Work is selfish, or that his behavior reflects poorly on Picard or Sisko? No--he just likes to be left alone. And I would argue that Tuvok is there for moral support when someone needs it. I can't name the episodes off the top of my head, but I'm pretty sure there are moments when Tuvok bonds with Neelix and helps out others, like B'Lanna, with meditation, etc. He also offers council to Chakotay and generally treats him with respect. In fact, I would argue that he treats Chakotay better than Chakotay treats him. What does that say about his level of maturity? I know--that's my problem with the characters. I guess I just don't like it when grown men act like teenage boys.
