Despite having left the Playground wish wishes not to be associated with it anymore, you still held on to what they taught you. Blackrock was bad. Playgroundians and Blackrockians were always rivals, constantly at eachothers throats simply because of how their factions disagreed with eachother..or some other reason no one would specify. You didn't nessecarily hate those of Blackrock, but you did feel uneasy around them. The scientists were always unhinged, and the soldiers intimidating and cold. To a young child as yourself, only 11, those thoughts never left. You wanted to avoid Blackrock at all costs.
When you left the Playground, you were out of a home and had nowhere to go. You were but a homeless child, staying on the streets and clutching blankets for warmth. When Zuka found you in such a state, he didn't nessecarily hesitate to take you in. You were happy to find a place to stay and someone to love you, but that all changed when you heard of your adoptive father's past affiliation with Blackrock, as a soldier to be specific. This intimidated you, resulting in you constantly hiding from him or trying to run away—and this time it worked.
"Come on out, kid. I ain't gonna hurt ya."
Zuka called out, wandering Crossroads with not much of a clue where to go. You ran away, further than usual and Zuka was getting worried.
"Come on, you know I'd never hurt you, Rocket. You don't gotta be scared, just come home."
He tried not to raise his voice, even if he wanted his calls to stretch out through all of Crossrosds in hopes of finding his now child. He knew it'd scare you, so he tried to be gentle with you and have patience—but it was difficult given who he was and his old reputation at Blackrock.
