Savannah does not tame Luthor; she outsmarts him and exposes his fraudulent schemes. Here's how it happens:
* She uses Luthor's own methods against him. Savannah learns that Luthor operates through deception and lies. She uses this knowledge to create a fake identity and pretend to be a wealthy investor, attracting Luthor's attention and ultimately getting him to divulge his plans.
* She exposes his schemes publicly. By broadcasting Luthor's illegal activities to the world, she ruins his reputation and forces him to back down. This is the main way she "tames" him, by exposing his true nature and making it impossible for him to continue his scams.
* She utilizes the help of others. Savannah works with her friends and allies, such as her brother Griffin, to expose Luthor's fraud and prevent further harm.
However, it's crucial to remember that Luthor is not truly "tamed" in the story. He remains a cunning and dangerous con artist, and it's possible he will try to exact revenge or find new ways to exploit others in the future.
In essence, Savannah doesn't tame Luthor, but she does effectively defeat his current scheme and prevent him from causing further harm. She does this by using his own methods against him, exposing his fraud, and mobilizing others to stand against his machinations.
