Chewie is closely related to the Skywalkers!?! =O
No, but he and Yoda go way back. I think Yoda was the Bacca family doctor and actually delivered Chewbacca. Who knows, Chewie probably has some Yoda DNA in him. There are 700 years of Yoda back story prior to Chewie's birth, anything could have happened. Then again, there are two hundred years of Yoda and Chewie backstory after Chewie's birth, maybe they Brokeback'ed it up and Yoda gave birth to Han somewhere in there (you never know how these alien reproductive systems work). Han could totally be an inbred, deformed, wookie/little green elf hybrid (which incidentally looks kind of human). That be totally wizard! Then Yoda would be Luke and Leia's great grandfather, as well as Leia's mother-in-law. It feels very appropriate and in line with established SW lore.
The thing you have to understand about the Star Wars universe is that red lightsaber means Sith, blue and green mean Jedi, and that everyone is closely related, it is just a matter of figuring out how.
