Acredito que a conversa entre Guinan e Worf resume bem a TNG Redemption Part 1 :
GUINAN: You know, I had a bet with the Captain that I could make you laugh before you became Lieutenant Commander.
WORF: Not a good bet today.
GUINAN: I've seen you laugh. I like it.
WORF: Klingons do not laugh.
GUINAN: Oh yes they do. Absolutely they do. You don't. But I've heard some Klingon belly laughs that would curl your hair.
GUINAN: Your son laughs. He's a Klingon.
WORF: He is a child and part human.
GUINAN: That's right. And you're not, you're full Klingon except you don't laugh.
WORF: I do not laugh because I do not feel like laughing.
GUINAN: Other Klingons feel like laughing. What does that say about you?
WORF: Perhaps it says that I do not feel like other Klingons.
{...]
GUINAN: [...] So how is he? Your son.
WORF: He is having difficulty adjusting to life on Earth.
GUINAN: I can see where it might be hard for the little guy. Living with humans, being Klingon. Could be very confusing.
WORF: It will not be easy for him.
GUINAN: No, it won't. But at some point he's going to want to know what it's like to really be a Klingon. Just as you're learning.
Durante a conversa, o próprio Worf diz que não se sente como os outros klingons. E um pouco mais tarde, Guinan aponta que Worf está apenas aprendendo o que realmente significa ser Klingon. Você pode ver isso mais tarde, especialmente no Deep Space Nine, Worf se comporta um pouco mais como um Klingon.
