How does what we know about Benvolio from act 1 manifest itself in act 3?

Benvolio is a peace-maker. He is able to sense violence when it is at hand and works to avoid it. He does this in the market in Act 1 at the market and he does this in act 3 when it is hot and humid outside. This is just before Tybalt shows up all angry to settle his score with Romeo.
