Hi. I just got caught up reading all 7 parts, too. I love this story! Very nicely written.
On the revelation, I agree with what you wrote at the beginning of this thread. I really don't see any reason for Lois to act with anger.
Regarding the kids, I kind of like your second option. It might be too early for Lois to interact with them directly (depending on where you go with the next chapters), but I very much like the idea of her observing Clark's interaction with them.
