"We'll see whose soul is who's with the passing time, my dear friend."

Filii's eyes roll back in his head as he embodies himself as a swarm of flies and swarms the other Elf boy whom he learned is named "Blaze"

The flies conjure back into Filii's living form, inches away from Blaze's body with his hand on the elf's shoulder 

he whispers
"Has anyone claimed YOUR soul yet, my lovely?"
His cold dead breath bouncing of the back of Blaze's neck
