In the Kill Bill movie, I learned, it is akin to the usual event when guy is most problably hitting on a girl, then comes this other guy and chimes in with some compromising/unbecoming story.
In a similar way this means that character doesn´t want to get distracted by this, he doesn´t it "block his intent", he wants to know the young guy. To get his own conclusions. It´s something like "thanks pushy guy, but I want to know the young guy and come to my our own conclusions.
I am glad that the cinephiles exist!
