Setsuna begins to research soot blight syndrome to understand the shocking statement Rinne makes. The endemic disease keeps the island isolated and toys with Rinne, Karen and Sara’s fates. But Rinne’s mother Kuon knows something unexpected.
It's the incense Sara was burning 
when she set out her futon.
إنه البخّور الذي كانت تحرقه سارة
عندما كانت ترتّب فراشها
Ah, die Duftstäbchen,
als Sara den Futon ausgelegt hat!
Es el incienso
que puso Sara junto al futón.
Es el incienso que puso Sara
junto al futón.
C’est l’encens de Sara,
à côté de son lit.
È l'incenso che Sara stava bruciando
quando ha tirato fuori il futon.
É o incenso da Sara, de quando
ela estendeu o futon.
Ароматная палочка у постели Сары!
