I have another few spare moments (not sure how many), so I wanted to respond while I have the time.
First off, let me remind you all that we're only on chapter 19. I still haven't finished, but this story will be at least 32 chapters (and that's me being conservative as I just finished 28 and I'm not sure how I'll ever wrap things up in four more chapters). So, don't be too sure that Lois and Chad are done for - there's still a lot of story left.
Sara - The fact that this was posted the same day as Carol posted the part with Chad getting together with Lana is pure coincidence. I wasn't originally planning to post yesterday as I didn't know how much running around we'd be doing to see family while away and thus didn't expect to have much time online.
Patrick - It's very unlikely that Chad and Lana will get together in this fic, not least of all because Lana is married to Pete and they have two kids. They've been married as long as Lois and Chad. While clearly that doesn't mean they have to still be together, it makes it unlikely that Chad and Lana will end up together.
Besides, this Lana is a bit more like the Lana we're all used to - she isn't evil mind you, but a bit less kind that the Lana Carol has created in OTOH. When Carol asked if she could use Chad for OTOH the main reason I was okay with it was that I felt that in recent chapters Lana had shown herself to be someone who sincerely cared about Clark and wasn't the type of person everyone speculated she would be at the beginning of the story. This Lana probably also wouldn't have told the news about Clark and Lois, but she would be more likely to. And I don't see Chad being attracted to that type of person.
The Chad Andrews at UC Davis is hilarious. How did you ever find him?
Ann - This is the place where I worried that you'd lose interest as I think the story stops being so "feel-good" right about now. The next several chapters are angsty, but necessary for where I want the characters to go. Lois and Chad have a lot to work through.
Michael - I'm surprised I surprised you. Not that I was trying to be too transparent, but I thought there were a few clues before now. And yes, this is where Carol and Kelly started calling me evil. They've stopped now, but I guess I don't know if that's as I've stopped being evil or they are resigned to my being so. If I had to guess, though, I'd guess the latter.
