Carl Gallagher, the fourth child of Frank and Monica Gallagher, blossoms into quite the ladies’ man as the show evolves.
He has a severe crush on Monica's lesbian lover, Norma, and sleeps with Meena Karib. Another notable conquest is the mother of a girl he was seeing in his last year of school.
However, he’s not always lucky in love. Early on he fell for Maxine, whose affections lay with his half-brother Ian, and then had to rebuff the advances of his closet gay friend Micky Maguire.
Suspected of a brutal attack, involved with an unfortunate incident with a stolen car, and failing miserably as a drug-dealer, Carl eventually makes the unlikely career choice to become a police officer.
However, his success away from the family doesn’t stop him answering his mother’s call late in the day.
