I loved this story. Whoever you are, thanks for writing it.
As for guessing, I don't think I'm going to be very good at it, but I'll take a swipe. At first I thought the humor reminded me of Queen of the Capes, but after reading Jojo's speculation about Sue...
I can spot Sue's Lois and Clark a mile away. Even if she does hide them in married couples, pregnant Lois, and Batman references. And if it isn't... they did an excellent job of throwing me off their track and I applaud them. Cause I laughed my butt off at this one. Just perfect.
I wonder if CC Aiken is still around. If she is, then this reminds me a bit of her dialogue style. Man, her banter between Clark and Lois always had me laughing.
Oh, and Caroline, you had me ROTFL with this deduction:
Then again, the Batman/Bruce reference could also be a red herring – the author wants us to think it’s Lara. But Lara would know that we might think it was a red herring, so maybe she put it in there on purpose, and who’s to say she hasn’t spent years building up an immunity to Iocaine powder...
