These guy just random popped up behind me when I had just bought myself a Dharma Swan badge (THAT'S RIGHT! I LOVE LOST!!) and asked for my picture. I was literally shocked coz I never thought these guys would bother an anime cosplayer like me.
I had the same thought in my mind too. I really love the old batman movies as well as the updated versions and I loved Nightwing coz he just looked so cool.
They looked like good mates too >_<
