Quote #10

JAQUES
The duke hath put on a religious life
And thrown into neglect the pompous court.
[...]
To him will I. Out of these convertites
There is much matter to be heard and learned.
[...]
So, to your
   pleasures.
I am for other than for dancing measures.
[...]
To see no pastime, I. What you would have
I'll stay to know at your abandoned cave. (5.4.187-188; 190-191; 201-203; 205-206)

This is interesting. The melancholy Jaques is virtually the only character who doesn't change. What's up with that?
