OOC:
Go ahead and describe as you please with poetic licence. Characterisation-wise whatever Helios thinks and says is fully true as far as he knows it. I'll use the successes of your rolls to affirm how much Helios knows. In this case, your Knowledge (Insects) will contribute to any Perception / Assensing tests about insect spirits by making the roll relevant to the knowledge area. You have 5 hits on Perception, I'll describe what that looks like.
"Interesting theory Mr Zen. We were told you possessed some degree of knowledge in this area." There were two other persons in the room when Helios and Hong arrived.
"I am Darius Chan, and this is Kumoi Mizawa." A older-looking bespectacled scientist who had been behind a test equipment station stepped forward, accompanied by an even older white-haired man with small eyes and walked with a limping, almost side-to-side gait.
"Come, we can enter so you may have a closer look." Hong keyed in a code, and all four men approached the table with the human insect restrained.
"Without speculating on the metaphysics of the matter, consider the features on this specimen. You are familiar with true form, which are spirits, and flesh form, which are insects with human hosts. This one looks like a flesh form, but with distinct differences." Darius waved Helios forward. Helios, given the chance to examine the body more closely, noted that the bug before him did not seem as if it was mutated from an original human body, as all flesh forms were. Helios had witnessed some of those mutations: human limbs would literally reform into insect appendages, sense organs like eyes would transform into multiple lenses, wings would sprout. This one before them did not bear any sign of metamorphosis. It appeared that it was a hybrid human-insect body, that both co-existed and grew together, inseparable. Perhaps it grew into adulthood from human insect reproduction, or perhaps it was a new evolutionary strain of human, or insect. It was not something Helios had seen before.
Helios' astral perception revealed to him an aura of the body as being both material and spirit. At the same time he understood that the room was hedged from the external astral plane, presumably as a means of protection and defence.
"On the other hand, if Mr Zen wants to discuss metaphysics after he's made his evaluation, I'd be happy to hear his thoughts." Mizawa smiled an inscrutable but friendly smile.
