With eight seasons rounding out Fear The Walking Dead and numerous surprises in the series finale, it's a good thing one particular past character was not brought back. The final season said goodbye to numerous characters, such as Morgan, Mo, and Troy, and welcomed back Alicia. Choices like these created opportunities for major characters to have more satisfying story ends and tied up overarching plot points. In the finale, Alicia's return, for instance, confirmed Tracy was not her daughter, concluded her and Madison's arcs, and reinforced the mission to help others that both Alicia and Madison's new legacy MADRE practices.
