Gregory & Sampson are provoking a quarrel with servants of the rival 'house'. One says - I'm paraphrasing: "Say 'better' - here comes my master's kinsman." Enter Benvolio.

Wait a minute - Benvolio is NOT his master's kinsman. Benvolio is kinsman to Montague, the master of the rival servants. The text has told us twice already that Gregory & Sampson are "of the house of Capulet". Tybalt, a Capulet, doesn't enter until several lines later.

To make these relationships clear to the audience, a director would either have to bring in Tybalt ahead of Benvolio, and let him stand around mugging while Benvolio does his bit, or have Gregory & Sampson pointedly looking in a different direction from that of Benvolio's entrance. Not that it matters a whit which servants are connected with which house in this scene - but why the confusion?

I've read that scene I-don't-know-how-many-times in the last forty years, and I just noticed this curiosity. So what do you think: did Willie or one of his editor's slip-up here, or is there some other explanation?
