At the end of the series, Kelso becomes one of the first characters to transition from adolescence to adulthood when he impregnates a girl with whom he had a one-night stand; much to his friends' surprise, Kelso accepted responsibility for the child, moving to Chicago to take a job to support and be near his... Kelso is one of the main characters in the sitcom George Lopez. He is best friend to George's character, Jeff Taylor, and they have been together since fourth grade. Although they are different types of people (Jeff is more quiet and serious while Kelso is more outgoing and lighthearted), they respect and support each other through their differences. In the beginning of the show, Jeff has a crush on Cindy Campbell but doesn't say anything because he thinks that she likes someone else. When Cindy's father, Dwayne, moves to Los Angeles after being fired from his job, she decides to follow him because she wants to become an actress. This makes Jeff realize that he loves Cindy and tells her so. They start dating but don't tell anyone about themselves because they think it wouldn't work out. However, when Dwayne finds out about them, he fires Jeff from his job as a security guard at a movie studio. This makes them break up but they later get back together.
