This one's a good concept.
Lois: (to amnesia'd Superman) You remind me of Clark so much.
Superman: You must have loved him.
Lois: Yes, I wish I had told him, though.
Superman: Could you tell me about him?
She (tells him about Smalville and what she knows about his travels and how much she was interested in him but didn't want to show it) and the memories return.
Someone, please take this concept on. I can see this being REALLY intriguing (and I have too many already on my plate as it is with finishing the Ultra Woman costume and five different stories up at the same time with more waiting in the wings).
CLARK: No. I'm just worried I'm a jinx.
JONATHAN: A jinx?
CLARK: Yeah. Let's face it, ever since she's known me, Lois's been kidnapped, frozen, pushed off buildings, almost stabbed, poisoned, buried alive and who knows what else, and it's all because of me.
-"Contact" (You're not her jinx, you're her blessing.)

. So many possibilities--I really hope someone takes this on.
