Actually there are strong evidences that Frog left a pregnant Ayla behind at 65000000 BC... Their child was known throughout the galaxy as Yoda, who happens to be Marle's grandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandgrandfather. And that's why the Force is so strong in the Guardian bloodline.
That makes the most sense EVER. Dosn't explain how Yoda got from the CT world to a galaxy far far away though.
Hey, maybe Queen Zeal had a sister? Being the evil witch with a B she is this woman was most likely killed once she gained power, but that sisters had a child and secretly braught the child to the earthbound village (or just hid around as a citizen of Zeal) before she died, and that child was one of the survivors? Seems to work as well as most other crazy ideas.
BTW Kino is definatly a relative of Marle, he and Ayla were just too good for eachother
"Ayla very strong!" -Kino (the Kinky)
