Kal-El did not immediately realize that he had entered another dimension. He was weakened by a kryptonite bullet and a battle with the Justice League from another universe.

The sun was shining brightly high in the sky above Metropolis... It was a different Metropolis – much like before the death of Lois and their unborn child. People were fussing and running about their business. This is another world, another universe, another dimension...

No one cared about the battle-torn Superhero – and Kal-El himself – Superman – was still trying to comprehend and analyze the situation. The wound from the kryptonite bullet burned his blood, depriving him of strength.
