This story woulod be confusing to you if you are not a DC Comics or science fiction fan. Superboy, the one to us was stabbed by Lex Luthor on one diension but rescued by another one on another dimension, a good Lex. Then the good Lex who is a doctor took him to see another Superboy in another dimension and that one saved his life. It was glorious.
The aging Superboy showed him to his world and it was grand. No wars, famine, crime, pollution. That Superboy, like all the othes came to earth at different times in their dimensions, through time warps. But our Superboy had to rescue the young one from Luthor’s exploitations ansd corruption and he did. He’s safe now and the aged Superboy is guiding him, to be a beacon for good.
The Lana on that dimension saw our Superboy change and had a lot of questions but the heartbreaking thing is that she’ll never get them answered as this ordeal is temporary and she’ll have an aching heart as Superboy may not come back. Maybe though, she’ll get answers through the young Superboy’s upbringing.
