Hey this is my first posting on the site so I hope I'm not about to make a rookie mistake, but I was thinking about star wars before I fell asleep last nightr and something struck me. At the end of ROTS you see Obi Wan take Luke and Padmes chief guard take Leia and they don't know about each other. So how come in episode 4 Leia sends a message via R2-D2 to Obi Wan? How did she Know about Obi Wan if he'd spent all those years watching over Luke? I haven't read any books and am willing to bet the answer lies in them, but anyone out there have an answer? May the force be with you all.
