This article looks at how a Black informal STEM educator supported two Black boys' learning opportunities in coding, specifically investigating how the establishment of politicized trust between the informal STEM educator and youth supported their development of critical agency. Using the dual lenses of socio-spatial relationality and politicized trust, we explore how the socio-spatial relationality of place, materials, and educator-youth interactions allowed for the shifting of power dynamics that were foundational to supporting youth in navigating a coding process that centered who they were and their interests, in the moment. We employ participatory design research aimed at reducing power dynamics by remediating who has power within a setting, grounded in dismantling and disrupting traditional power hierarchies through actively involving the community in the design process. We present two case studies that map the learning trajectories of Donovan and Jabria, two middle-school aged Black boys. Their learning trajectories include the following phases: tensions related to coding with Scratch, pivotal interaction with the educator, and development of critical agency. We unpack how the socially produced space supported Donovan, Jabria, and Worsley to critically read the world of coding, rewrite coding through political action, and establish politicized trust. Throughout this process, we see through Donovan and Jabria's interactions they were constantly editing and producing their interactions with coding which led to newly created learning opportunities by developing their critical agency in coding. Four main points were identified: continuous access to materials, sustained engagement to reimagine possibilities, understanding that all disengagement is not equal, and being explicit in communicating expectations followed by concrete action. Across these points, the salience of relational politicized trust between educator and youth was a cross cutting thread.
