Quote #4
MOTHER
Peevish, coy, foolish! But return this answer:
My lord shall be most welcome, when his pleasure
Conducts him this way. I will sway mine own;
Women with women can work best alone.(2.1.264-267)
Castiza may be brave enough to hold out for what she wants, but her mother seems really worried about being poor—so much so that she's willing to pressure her own daughter to have sex for money. From a character perspective, do you think she's right that Castiza is more likely to cave in to pressure from her mother than bribes from Lussurioso?
Quote #5
VINDICE
Night! thou that look'st like funeral heralds' fees
Torn down betimes i'th' morning, thou hang'st fittly
To grace those sins that have no grace at all.
Now 'tis full sea abed over the world;
There's juggling of all sides.(2.2.147-151)
Vindice thinks that practically everyone is having illicit sex. Seems like there's something unhealthy about his obsession with it—they might be having it, but he's the one thinking about it nonstop.
Quote #6
VINDICE
[…] This very skull,
Whose mistress the duke poisoned, with this drug,
The mortal curse of the earth, shall be revenged
In the like strain, and kiss his lips to death.(3.5.103-106)
This is getting seriously creepy. Vindice plans to trick the Duke into kissing the poisoned skull, believing it to be a living woman (those must be some seriously low lights). But the big point is that, as usual in revenge tragedy, the Duke will be undone by his own sins as much as by Vindice's plotting. Lust made the Duke kill Gloriana, and lust will bring him to the place where Vindice kills him.
