Franklin is Kady's playmate and "boyfriend" first introduced in season three's "Jay the Artist". Franklin is a child prodigy, who is very skilled at playing the piano, which usually amazes first-time listeners, and is generally very intelligent, so much so that he had accomplished attending and graduating from Harvard University before the age of 7. Franklin has very strong feelings for Kady and sees her as his everything. He loves Kady with all of his heart and often says poetic comments to Kady, which often led Jay to slap Michael across the shoulder asking him "Why can't you be more like Franklin". Running gags involving Franklin include him uttering "Isn't she great"?, "Anyhoo" or "However" in a drawn-out tone when trying to change the subject or when he sees that he is talking with someone less-than-intelligent, which has also been used by the other Kyle family members, usually Michael, on occasion. When he tells a joke but no one laughs, he says it's funnier in Latin. Franklin has a younger sister named Aretha (Jamia Simone Nash), who herself is an impressive singer; Frankin however does not think Aretha is a good singer however, thinking Kady is a better singer, which Michael tells him in season three's "Sharon's Picture" is because he is in love with Kady and Aretha is just his sister. It is mentioned that, unusual for someone Franklin's age, he is a certified contractor and was able to coach Michael and Junior how to deliver Junior's fiancee Vanessa's baby due to his medical knowledge. However, Franklin did find it hard to fit in with other children his age and even seeks advice from Michael, who is usually the one who seeks advice from Franklin whenever Michael gets himself in a tight situation, on how to act more like a normal kid in the season four episode "Junior Sells His Car".
