mark healy ii is portrayed by ames mcnamara. the younger of darlene's two children, mark is a 10-year-old boy with a strong interest in fashion. his interest in things traditionally feminine, such as wearing makeup and skirts, is somewhat worrisome to his grandparents, with roseanne worried that mark will be bullied by his narrow-minded peers and dan feeling that he needs to persuade the youngster to take on more masculine traits. noticing a classmate make a snide comment to mark on his first day at school in lanford, roseanne threatens his classmates by telling them she's a witch, while dan gives mark a pocket knife, which ultimately results in him being called to the principal's office and sent home from school for the day, much to darlene's chagrin. despite roseanne and dan's concerns, they express support and love for him. mark is named for his deceased uncle, mark healy.
