Don't shoot me! You'll have the sequel next week! What? You thought she really had lost her memory? Sorry. I wasn't trying to pull a fast one. I figured that as soon as I said "John Doe" everyone would know it was really time travel. I just didn't want Lois or Clark to know that.
Oh! And I have to say that the inscriptions on the rings were shamelessly stolen from "First Comes Marriage" by ML Thompson.
