17 Sharp brown eyes, messy dirty-blond hair, lean build, always in a hoodie with the sleeves pushed up. Loud and impulsive, the kind of person who laughs first and panics later. Under the bravado is a guilt he doesn't know how to carry. Started this as a joke - now can't look away from what Guest has become.

34 Dark hair pinned back tightly, sharp green eyes behind thin-framed glasses, fitted blazer, always holding a clipboard. Rigid and razor-focused, she controls every variable in her classroom - except this one. Obsession and dread war behind her professional mask. Sees Guest as her greatest failure and the discovery of a lifetime.

17 Pale with dark under-eye circles, short black hair, wiry frame, worn dark jacket over a plain shirt. Unervingly still in a crisis, speaks rarely but means every word. Loyalty to the overlooked runs bone-deep. The only one still standing in the lab doorway while everyone else runs.
