421预告片里根妹说的Keep fighting，让我想起Fred在Angel第三季第七集的台词。
Can I say something about destiny?
Screw destiny!
If this evil thing comes we'll fight it, and we'll keep fighting it until we whoop it.
'Cause destiny is just another word for inevitable.
And nothing's inevitable as long as you stand up, look it in the eye, and say "You're evitable!"
我能不能说说有关命运的事？
让命运见鬼去吧，如果邪恶来临，我们将与其战斗，直到把它打败。
因为命运只是“不可避免”的代名词，没有什么是不可避免的。
只要你站起来，抬起头对着它说：“你是可以避免的。”
