chained together by fate, childlike naivety, and a set of really cool masks. Sure you can argue Terapagos is the main driving force behind the entire Area Zero plot, but with characters like Heath or Sada/Turo being all fucking dead it makes him feel completely disconnected to the rest of the cast.
