First of all, before you flame me, Masashi Kishimoto said himself in an interview that he created Deidara and Sasori for each other. They are a true (canon) pairing!
I got the idea for this from a gag comic I saw about Sesshomaru vs. Itachi.
I noticed how alike Kimblee and Deidara were and then me and my best friend started arguing about which terrorist bomber was better. It was hilarious. These were some of the similarities we came up. Finally, I grinned and said the final one. VICTORY!!!! ^0^!!!! (That means that Deidara wouldn't be in love with her because he's already taken! XD!)
