Luke struggles to pry out something that's jammed inside R2, setting off Leia's message. Is that supposed to be the death Star plans hidden in the droid? Because that's not where Leia put them.
First Owen says he doesn't know what R2 is talking about when he mentions Obi-Wan Kenobi. Then he says that Obi-Wan is dead. Is Luke buying any of this? More...
Most of the things Obi-Wan tells Luke about his father in Episode IV turn out to be true, at least from a certain point of view. Except for that business about Skywalker Sr. wanting Luke to have his lightsaber when he was old enough. If Anakin had any such wish, he couldn't have told it to Obi-Wan since the latter didn't even learn about Anakin's pending fatherhood until after the two Jedi were beyond the point of making friendly small talk.
On a space ship, "down" is determined by artificial gravity. Therefore, if the ship is damaged and begins to tilt, those inside would not begin to slide across the floor; gravity would keep them oriented to the floor, no matter what position the ship was in. The only way our heroes could experience the "Poseidon Adventure" effect would be if the artificial gravity controls malfunctioned. And what a strange malfunction, as the gravity continues to shift a millimeter at a time until everything is upside-down!
"Only a Sith deals in absolutes," cries Obi-Wan, although his statement is itself an absolute.
