What was time?
To Barry Allen, time was the river beneath his feet, a track he could race along at will, a weapon he used to save the world.
But now, time had become... a wall.
An invisible, intangible wall that was everywhere at once.
He was still running.
He could clearly feel the Speed Force burning wildly inside him. Every cell vibrated beyond its limits, driving him to one new peak of speed after another.
His body still lunged forward, muscles taut, arm outstretched, fingertips almost touching the green button that meant victory.

Yet now it was the greatest distance in the universe, an impassable chasm.
The faster he ran, the more solid that chasm became. The harder he pushed forward, the more clearly he felt the despair of being pinned in place.
He was like an ant trapped on a Möbius Strip, believing he was moving forward when he was only following an Infinite Loop back to the starting point, again and again.
