Disclaimer: I don't own the Gallagher Girls.

Every Gallagher Girl knows that Cammie's dad was a spy. Every Gallagher Girl secretly burns with curiosity to know what happened, even Cammie, not because they enjoy hearing tragic stories, but because it is in their nature to know, and find out what they don't.

For spies, curiosity can be good or bad. It can be helpful or deadly.

It can between the difference between success and failure, smooth and disastrous.

Knowledge, too. It goes with curiosity. It has two sides to it, like a magnet. When you're a spy, the saying, "What you don't know can't hurt you," is a lie. It gets cancelled out. The unknown can hurt. It can kill. Spies don't go in without background information unless absolutely necessary.

Every Gallagher Girl knows this. They all know about knowledge. They're informed of curiosity. They consider every angle of things with curiosity and knowledge in mind to be sure of their facts. Unfortunately, sometimes things get in the way. Every Gallagher Girl knows that, too. When you're a spy, a girl, and a teenager, life is complicated. It's messy if you don't eliminate the source of the problem. Every Gallagher Girl knows that sometimes, this source can be a person.

And often this source is innocent. Often the source is only a distraction, someone who diverts attention from the job that needs to be done. Often they are guilty of nothing more than saying, "Excuse me, miss, have I met you?"

Often this source is a boy.

Every Gallagher Girl knows this. One knows it more than the rest, because she knows from experience what happens when boys get involved. Whether they are seemingly normal boys in Washington D.C., or whether they are small town boys—or whether they are Blackthorne Boys.

All three are distracting. All three are dangerous. And all three can be deadly.

Every Gallagher Girl knows this. But Cammie Morgan knows it best.
