doesn't make sense
there's still one thing that bothers me: when luke leaves degobah in order to rescue han, leia, et al, obi-wan and yoda converse as luke's x-wing takes off. obi-wan says, "he is our last hope." yoda disagrees, rebuking him,"no, there is another."
how could obi-wan not know about leia? when lucas filmed empire, it was possible. however, then he contradicts himself in episode iii by placing obi-wan at padme's side when she gives birth to luke and leia.
have been on the message boards (theforce.net and starwars.com, among others), and have yet to find a satisfactory answer.
anyone?
