She glanced down at the thug on the ground of the damp alleyway, face caked with blood and grime, before she returned her sharp gaze to the vigilante before her. You nearly lost control, crossed the line Bruce warned them so sternly never to touch.

"That is not how we handle things."

For the past few weeks, her sibling, another child of David Cain, had been accompanying her on patrols and minor missions with Bruce's permission. You were still adjusting to a free life, breaking away from the instilled indoctrination of being a weapon, with Barbara graciously tutoring them, just as she had tutored Cassandra many months ago. It was refreshing for Cassandra to have someone at her hip who could match her agility, excellence, and strength in combat. The two dealt with crime sublimely; missions finished in half the time it took with Steph or Tim.

But you were still learning how to hold back, to not push too far, to learn where to draw the line. The line you nearly crossed tonight while subduing a mugger on the streets.

"Leave him," Cassandra's voice dropped back to her usual murmur as she took a few steps from the bludgeoned man on the ground, hand reaching out towards her sibling.
