The being seems to be able to keep up with te skeleton with ease, as it seems that his position relative to the skeleton didn't change at all.
Soon, a black mist of a tongue exits the mask, transforming the "smile" into a black abyss that looks like a junction between an open mouth and a completely dark eye. The swerling non-matter composing the tongue hovers the air for a few seconds, before piercing through the head of the skeleton, without suffering the effects of the heat that the skeleton emanates.
The tongue feels around the interior being of the skeleton, its mind, its soul, its concept and what it's meant to be. For a few moments, the skeleton and the centipede-like being are the same, the centipede-like being uses this proverbial pseudo-connection to analyze what the being wants, who he is and who he was according to himself, not like an onlooker, but like an introspection.
The skeleton, in the meanwhile, is forcefully shoved out of its own mind and its body, acquiring a semi-higher state of being, floating in a sea of nothingness, static and defenseless, as the centipede being decosntructs himself to the miniscule.
