Ay, lord, she will become thy bed, I warrant, 1485 115 And bring thee forth brave brood.
We're all very sympathetic to Caliban, but he does attempt to use Miranda as a bargaining chip here, specifically selling her out for sexual purposes to Stephano. Its interesting that Miranda is made a sexual object by Caliban and Prospero, who hates Caliban for his attempted rape of her. Ferdinand isn't sexless, but is far less threatening as a white guy and prince. Prosper approves of him for those reasons, as well as the fact that he's in control, ]since he wants Ferdinand to fall in love with Miranda so he can exploit their courtship for power.
