SPOILER ALERT for anyone who still hasnt watched the last few episodes of Galactica:
I cant believe I missed this connection before, but the scene toward the end of season 4 where Starbuck is sitting next to a mysterious stranger who may or may not be her father actually has a parallel in the original series; heres the original Starbuck sitting next to a mysterious stranger who may or may not be his father:
(And yes, thats Fred Astaire as maybe-daddy.) Of course, the stories behind these two mystery-dads turn out to be deeply different; Astairebuck is a solid flesh-and-blood guy with no connection to the ship-of-lights folks. Still, it looks to me like this is one more homage to the original series.
