Jae can't quite see that far, for better or for worse - he's a bit distracted by struggling forwards, towards the cracks in the riverbed wall, and by necessity, the creature's heart. When it begins to tear apart he can only see one side of it, blood and viscera floating into the matter he's trapped in - the tentacles that have him begin to release, but the metaphysically transformed dirt begins to solidify again, and Jae-- is pretty stuck, and lightheaded from lack of oxygen--

He grabs hold of cracked concrete and tries to pull forward, his vision going back, and realizes with a distant thought his hand is still bleeding, before his body gives up and forces him to take in a breath in seizing involuntary self-defense, and he chokes.
