Jenny presents another ironic twist on a classic archetype: the prostitute with a heart of gold. Just as Macheath is an ironic hero and Peachum is an ironic villain, Jenny is an ironic prostitute with a sentimental heart. Like the archetype, Jenny is a good girl who is sweet and caring about her former love and pimp, Macheath. Unlike the archetype, though, Jenny is willing to hand over Macheath to the cops in exchange for cash. She cannot resist pursuing her own self-interest like everyone else. So, Jenny chooses money over loyalty to Macheath. She, like Polly, is conflicted between self-interest and love, even though she ultimately chooses self-interest.
