What threads did the Lois and Clark: NAoS show leave dangling? And how many of them were there?

1. What happened to Cat?

2. What happened to Jack?

3. Where did that baby come from?

4. If Martha and Jonathan were heading to Italy for their anniversary at the end of S2, why were they back in Kansas when Clark calls them for advice about his rejected proposal / botched revelation at the beginning of S3?

5.(a) Why did Perry hire Ralph?*
5.(b) Why did Perry hire Wally?*
and not Clark?

6. Was S1 Jimmy supposed to be the same person as S2-4 Jimmy?

etc, etc, etc.

Extra bonus challenge: Write a story tying up one of these loose threads? /even if the topic has been addressed before/
