This page is about the US incarnation of Sheila Jackson. For the UK version, see Sheila Jackson. Sheila Jackson is a former main character, appearing in seasons 1 to 5. She is introduced as the agoraphobic mother of Karen Jackson and becomes Frank's main love interest for the first five seasons.
Sheila has agoraphobia, which she developed sometime during Karen's childhood. Due to her agoraphobia, Sheila has a fear of the outside world and is unable to leave the house. Sheila takes pleasure in sexual activities and taking control, something in which Eddie and Frank find no pleasure. Sheila is introduced in the pilot episode as the mother of Lip's promiscuous girlfriend, Karen.
Karen reveals to Lip that Sheila is agoraphobic and has a fear of dirt. Angered and disgusted, Eddie chases the boys out of the house, then later packs his bags and moves out, upsetting Sheila.
Sheila gladly invites Frank into her home and, after the two flirt with each other, Sheila initiates a sexual encounter with Frank; it is revealed that Sheila has a kink for sex toys and being dominant. Sheila continues to act coldly towards Eddie, still upset by his previous actions. The babysitting initially goes well until Liam ventures off outside and wanders into the front yard while Sheila isn't looking.
Sheila is terrified of leaving the house to save Liam; however, acknowledging that Liam could potentially get into danger, Sheila musters enough courage to briefly go outside and retrieve Liam from the front yard.
