Great story! The plot is really great, it is really well written. I really like the explanation of what was really happening. The last line made me laugh.

You just wrote a Harry/Luna (ding!) epistolary fic (ding!) that crosses over with Carmen Sandiego (ding!) and Where's Waldo (ding ding ding we have a winner!).

Marry me?

Cute story, and I liked the punchline!
