I don't know if this story made it to the archives, but it was excellent.

It takes place during the pilot, when Lois, Clark and Lex are in his study. Lex and Clark are having a conversation and about Alexander the Great and I think it ended up being a duel of words regarding Greek history.

Any ideas?

Oh I love this fic! And yes, it's in the archives.
Xerxes the Great by the Quiz Master, Susan Young.

It's a really good story. The tension between the two leads is palpable... Two alpha males is their prime! I sadly realized while reading it how little is left of my five years' studies in ancient Greek literature, sigh...

Oh! What a pleasant surprise! Thanks for the positive feedback.
