Smallville :

Upon discovering that Professor Fine is in Honduras, Lex sets out to confront him. Meanwhile, Clark meets a beautiful seductress named Simone who uses a magical charm to make people succumb to her every wish.

When the hypnotized Clark reveals his powers to Simone, she seizes the opportunity and orders Clark to kill Lex. Lana breaks up with Clark because she entered on him wearing nothing but his boxer shorts with Simone in her underwear too kissing each other on the couch.
