Great part! I'm so glad Lois and Clark are back together.
Wonderful way to let him know that they're expecting (coincidentally, I love how you had her saying 'we' all the way through).
I was a bit disappointed that Clark didn't get to see Ren again, but at least Xena told him Clark's name so that he knows his friend was thinking of him.
And, I have to admit that I was wondering why we had needed the thief if we could just get the time-window from Tempus, but of course, it had to break!
I do wonder what Xena and Gabrielle are thinking of Lois and Clark at this point and all the differences they've seen in them now.
Only one more part? Looking forward to seeing how they get home!
