Ohhh, it was a Wells set-up! Not what I was expecting at all! (My theory was that it was all a dream or hallucination, perhaps AltClark's mind's way of dealing with the trauma of his own universe's Nightfall, an alt-world reaction instead of our Clark's amnesia.)
It all worked out fine in the end, though, with Alt Clark getting a little break to emotionally refuel, and then he comes back home to find his Lois. A happy ending all around.
Thanks for sharing it with us!
