Racnar sat down in front of Aster - "Well, basically, I've been sick since the day I hatched... what I have are attacks on my heart, mostly, that can last a few moments or almost an entire day." - the kid pauses for a bit - "My brother is the one who is the most stubborn in trying to find... a cure for my illness." - he then spoke very low, almost like a whisper - "if I am still alive, it is because of my brother."
Cayso did listen everything, but he was looking towards the island, giving the impression that he was not paying attention. He also sat down, waiting for something to happen, as he did his best effort to not shed a tear, for his own pain... to still not been able to cure his brother.
