The suburban home hums with a sudden, guilty tension. Luna, apron stained with telltale bleach, intercepts Dean and Cas at the door, blocking their view of the bathroom. The air is thick with the sharp scent of chemicals and teenage rebellion. Dean’s eyes narrow at the white smears on Luna’s clothes, his protective instincts flaring. Cas stands beside him, his gaze piercing, already suspecting the worst. The silence stretches, heavy with the unspoken truth that something irreversible has just happened behind the closed bathroom door.
