Os nomes que você conhece primeiro são difíceis de abalar. Luke conheceu Obi-Wan Kenobi pelo nome Ben Kenobi e é assim que ele sempre pensa nele. Isso é semelhante a como os hobbits em O Senhor dos Anéis continuam a se referir a Aragão pelo nome Strider mesmo depois de aprenderem nome verdadeiro.
Do script de filme Star Wars :
THREEPIO: He says he's the property of Obi-Wan Kenobi, a resident of these parts. And it's a private message for him. Quite frankly, sir I don't know what he's talking about. Our last master was Captain Antilles, but with what we've been through, this little R2 unit has become a bit eccentric.
LUKE: Obi-Wan Kenobi? I wonder if he means old Ben Kenobi?
THREEPIO: I beg your pardon, sir, but do you know what he's talking about?
LUKE: Well, I don't know anyone named Obi-Wan, but old Ben lives out beyond the dune sea. He's kind of a strange old hermit.
Em The Empire Strike Back , Luke conhece o verdadeiro nome de Obi-Wan, mas ele reage e responde para o seu fantasma como Ben Kenobi:
Luke lies face down in the snow, nearly unconscious. Slowly he looks up and sees Ben Kenobi, barely visible through the blowing snow. It is hard to tell if Kenobi is real or a hallucination.
BEN: Luke...Luke.
LUKE: (weakly) Ben?
BEN: You will go to the Dagobah system.
LUKE: Dagobah system?
BEN: There you will learn from Yoda, the Jedi Master who instructed me.
The image of Ben fades, revealing a lone Tauntaun rider approaching from the windswept horizon.
LUKE: (groaning faintly) Ben...Ben.
