how is henry v conceited throughout shakepreares play ?

"Thou hast me, if thou hast me, at the worst; and thou shalt wear me, if thou wear me, better and better."

There's for thy labour, Montjoy.

Go bid thy master well advise himself:

If we may pass, we will; if we be hinder'd,

We shall your tawny ground with your red blood

Discolour: and so Montjoy, fare you well.

The sum of all our answer is but this:

We would not seek a battle, as we are;

Nor, as we are, we say we will not shun it:

So tell your master. (3.6.7)
