What a fun story. Thank you for sharing it with us. "The Incredibles" and L&C are each delightful in their own right, but when they are paired together under your expert pen, the result is a story that left me with "the biggest, stupidest grin on <my> face."
I think you were spot-on in describing what Clark's reactions to the movie would be.
Incidentally, as a parent myself, I loved Edna's and Clark's comments about parents and heroes. Although I have long considered parenting the most important "job" one can have, I have never particularly thought of it as heroic before. ("I'm not being a hero; I'm just being a Mom.") It's fun to see Clark's take on the topic, since he is clearly both a parent and a hero.
I, too, hope there is a third movie. I also hope that if there is, you will write a third story in this series.
Joy,
Lynn
