Sayaka deep in conversation with Kyubey before her showdown with Homura.
INCUBATOR: You know you can't win this. It's suicide.
SAYAKA: I'm now older than Kyosuke ever was. This may be the only thing I do that matters.
INCUBATOR: 2 years of fighting witches, amounts to nothing?
SAYAKA: Witches are like weeds, pull one out another grows in its place. This, is about the future of the world. It's my legacy. My father told me a story once, about what our ancestors did for a living.
INCUBATOR: They were farmers?
SAYAKA: No. First generation, made their fortunes trading with the Americans. Pelts, skins and rugs.
INCUBATOR: ...
SAYAKA: They were hunters.
