Wow. Ten lost years! And they accidentaly meet as Clark interviews with Perry!
Indeed, Laura, this is a bittersweet ending, but it's an excellent one at that. In all this time, Lois has never revealed her knowledge of Clark's abilities, so he knows he can trust her in that regard, but I wonder how long it will take for him to fully trust her with his heart again. Even a hurt this deep can be healed, but it doesn't happen overnight. And while you might be concerned that the ending seems rushed, please don't be, because this isn't the ending. As others have pointed out, the fact that she knows about his abilities and the fact that they already have a history changes everything.
And don't sell your writing short. This is an excellent piece of work, and I think it's better than some of the stuff I've seen lately that people want you to pay real money for. (I go to the library a lot and stand around in bookstores.) I sense a Kerth nomination next year.
