Clark and Lois are engaged to marry. After coming so close to disaster during Brainiac’s attack, they realize they should have done it much sooner. While planning, they are both confronted by a Fifth-Dimensional imp, Mister Mxyzptlk, who challenges the couple to prove how strong their love is, and whether it really does conquer all, and it ends up being Mxyzptlk showing them what their love truly means, after sending Lois to a world where she was the one with powers, and Clark to a world where the two never went on their first date and Lois moved away from Metropolis.
