In Kill Bill Vol.2, when Bill calls his brother Bud to offer him support and to warn him about Beatrix seeking her revenge, he refuses saying:
That woman deserves her revenge. And we deserve to die. But then again, so does she. So, I guess we'll see, won't we?
Bill asks him about his Hattori Hanzo sword. Budd lied and claimed he pawned the sword (for $250). Why would he lie?
