Overview:Violence and compassion commingle in this insightful episode. In the main plot, a rebellious, Irish-American teen squares off against an offended, African-American classmate in a racially incited brawl that distresses their caring teacher and leads to a more contentious fray with principal Harper. In other storylines, Winslow teachers undergo peer evaluations where Ronnie reluctantly grades Zach, with whom she has a somewhat romantic involvement; and Marla seeks to arrange medical help for a hearing-impaired student, whose parents aren't receptive.
