Hmm... Clark as a Lane could be Backwards. For whatever that's worth.

There is a fic where Lois is Kryptonian and so is Clark. They think they might be siblings. I forget the resolution. It was a Kerth nom though. I think Pam might know which one - I remember her loving it.

The On the Other Hand universe has Clark with a brother but no twin.

I started a fic with Clark and a twin who worked for NCIS [and hence a mild crossover] but it's still languishing on the hard drive. Where it will likely stay. I don't remember how I'd planned to resolve the CK=S business. But this was going to come to into play: Now, As Before .

I was waiting for Coin to be done before reading it [because of my own idea] but... frown
