 When Kerrigan returned to Char, Zagara challenged her authority due to her regained humanity, thus deeming her unworthy to lead the Swarm.Once defeated by Kerrigan, the broodmother was forgiven, and she rejoined Kerrigan's Zerg Swarm forces.Her renewed loyalty is not left unrewarded though, as once Kerrigan ascends to become a Xel'naga, she relinquishes all command over the Zerg Swarm to Zagara, making her the new "Queen of Blades", but only after being evolved by Abathur and subjected to Kerrigan's teaching her some lessons.
