This topic's all about Convergence. For those not following comics these days (and a Lois/Clark fan doesn't usually have much of a good reason to follow the current comics), they're in the process of ending the "New 52" titling. To do so, they've created an event that pretty much pits different versions of the characters in "battles" with one of them getting to live to the post New-52. In "Convergence: Superman #1" we get to see the pre-Flashpoint (also known as Post-Crisis, BTW) Superman and Lois. From here on out there's a spoiler warning. I'll post the rest in it's own response.
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.)
