I always thought it would be cool to see a connection between KB and some other Tarantino movie. But not in the obvious way. More like in the RR-PF way. You know, the Vega brothers etc. For example seeing a grownup black woman whose mother has been murdered in front of her, when she was five (the girl, not the mother), but not as a main character just some random other character. We, the QT freaks, would geekgasm at the theatre, but it wouldn't be a lame "Kill Bill 3", just a subtle hint.
I'm not sure if what I said was clear, but there you go.
