I hope they explain how Husker became Husky.
I had assumed it [the callsign] was because of the gravel / growl voice but in part one Coker referred to him as 'a husker' and Bill told him he's from Caprica. As for the Voice - I guess He eats Cylons for breakfast.
About to see the second part. I like it so far. Good fun seeing Galactica in her prime.
