Allan Willis is the Willis' son and older brother of Jenny. Andrew Rubin appears as this character in the first season finale of The Jeffersons, in the episode titled "Jenny's Low" (aired on April 12, 1975), in which he returns from Europe, and is given the "Cold Shoulder" by his sister, Jenny (Berlinda Tolbert). Jenny starts staying at the Jeffersons' apartment as long as Allan stayed at their own home. She was somewhat jealous of Allan turning out to be "white". They eventually reconcile.
