How about option 5a, AnKS? The DP blows up and Lois is caught inside? Not sure what happens to Clark in this possibility, but if Lois dies, I don't need to figure it out as our narrator is gone.
Okay, that isn't the option I went with. You'll have to wait for tomorrow to see which one I did (I will say I wasn't so creative as to come up with something not on your list).
