I don't know exactly what to say other than "I'll miss you, hon".

 Cetas had been struggling for some time: both while he was taking care of his beloved mother and, later, once he grew ill with his own sickness. I have heard that he died yesterday, the 20th of June, 2019, and it was suprisingly sudden. He was trying to fight an infection while he was in the hospital and, in the end, succumbed.

I'll miss you so much, sir. You were a good man with a deep heart.

Yours,
Sylvan
