Book 5, Chapter 38: Sidekick to a Spirit Quest

Sometimes, we're the hero in our own story, and sometimes we have to be the sidekicks in someone else's. Doesn't mean you can't use the dress again, later!

A wedding is about the bride, so no matter what the bridesmaid's dress looks like, you just nod and smile. But not when she tells you that "You'll be able to wear it again for something else." If you want to make that joke, you need to, I don't know, go to the basement of the CIA headquarters to make it.

Or post the pictures on the Internet.
