Johnny manages a last gulp of air before Zagreus drags him back down, and he holds it tight as they sink together. Zagreus evidently doesn't need air like he does, and he feels another surge of fear at the realization, that Zagreus will keep him down until this is done. This won't be the first time he's died in one of these fucking dreams, not by a long shot, but it never hurts any less and his desperation to survive never leaves him. He writhes helplessly against Zagreus' hold, his lungs burning, reaching pleadingly back toward the surface, while all around them the pleasant glow of luminescent plankton swirls in their wake.
