One with the environment. One of the most valuable skills in espionage. You can gear up with the best swag out there - but it is an unteachable skill to belong anywhere. The other edge of what is the unfortunate truth: You must first belong nowhere.
I hope you all have a very Merry Christmas and Happy Hanukkah! 2014 has been a wonderful year and I only hope for even greater things in 2015. I am so glad this fandom exist, you guys are all amazing people. Cheers XO
