Case file · Who is who
Season 4 · 2006 · The school
Four thirteen-year-olds start eighth grade at Tilghman Middle, where Prez is a rookie math teacher. Outside, Marlo owns the west, Carcetti runs for mayor, and the detail is down to almost nobody.
This page says who people are, not what happens to them, so it is safe to read mid-season. It does assume the previous seasons have been watched. Cards marked “later” are people who only show up in the back half of the season.
