H.P. Lovecraft and Isaac Newton are stuck in Flooded Subway Tunnel and forced to have a deep conversation.

"Good heavens, Newton, this aqueous abyss reeks of something far older and fouler than mere decay," Lovecraft shuddered, pulling his coat tighter.

"The water pressure, sir, is calculable, a force demonstrably governed by gravity and fluid dynamics, regardless of its olfactory unpleasantness," Newton retorted, adjusting his wig.

"But can your equations account for the lurking geometries, the angles that defy Euclidean understanding, that this place seems to exude?" Lovecraft countered, his eyes wide with unease.

"Geometry is geometry, sir, whether inscribed on a page or manifested in a dank tunnel; its principles remain immutable, even if poorly perceived," Newton affirmed, unmoved.

"Immutable? Tell that to the squamous horrors that surely writhe just beyond the reach of our flickering lamplight, creatures born of dimensions we dare not name!" Lovecraft whispered, his voice trembling.

"Creatures, sir, are composed of matter, subject to the same universal laws that govern the planets; their existence, if proven, would merely expand our understanding, not invalidate it," Newton stated, ever the pragmatist.

"But what if these laws are merely a veil, a comforting delusion masking the true, chaotic nature of the cosmos, a nature that would drive us mad to comprehend?" Lovecraft pleaded, desperate for understanding.

"Madness, sir, is a disorder of the mind, perhaps caused by an imbalance of humors; it is not an inherent property of the universe itself," Newton replied, dismissively.

"Then you see nothing, Newton? No hint of the vast, uncaring indifference that permeates all existence, the cosmic horror that dwarfs our petty human concerns?" Lovecraft lamented, despair creeping into his voice.

"I see the interplay of forces, sir, the elegance of mathematical relationships; and I trust that even in this submerged and disagreeable location, reason shall prevail," Newton concluded, his gaze fixed on the rising water.
