You don't have to state friendship to be friends. Screen time isn't required to establish friendship. And if you want to use that argument, Anakin had plenty of that as well with Yoda. Two things. 1. The novel is wrong. Obi-wan knows before he looks at the recordings which is why he says that he must know. And the film trumps the novelization about Anakin know that Obi-wan is still alive. You have conflicting pieces of dialogue here. ANAKIN: "I will not betray the Republic . . . my loyalties lie with the Chancellor and with the Senate . . . and with you." PADME: "What about Obi-Wan?" ANAKIN: "Many Jedi have been killed." PADME: "But...Are you sure? It seems so...unbelievable. " ANAKIN: "It's all true Padme. I was there." PADME: "But...but how can that be true? How could Obi-Wan be involved in something like that?" Which is the opposite of what is in the film. ANAKIN: "I will not betray the Republic . . . my loyalties lie with the Chancellor and with the Senate . . . and with you." PADME: "What about Obi-Wan?" ANAKIN: "I don't know . . . Many Jedi have been killed. We can only hope that he's remained loyal to the Chancellor." So which is right? The film written and directed by Lucas, or the novelization written by Stover. Remember, Lucasfilm policy is that the films come first and if the books contradict, it is the fault of the books and not the films. 2. The ROTS novelization has 451 pages of story and one more page that is not numbered, that contains the passage about love conquering the dark. After that is the chapter sample from "Dark Lord: The Rise Of Darth Vader".
