Loli exchange program. Personally i think Touma should have kept the other one and then go for the whole set, he'd only be missing the mother.

Touma gets denser each episode, how can you just calmly buy a girl jewelry? Buy her a hat if you want to tell them apart you dumb fuck.

Next week's preview seems to indicate more action is on the way, and i can't help but wonder how the hell the blonde guy will manage to get accelerator to bleed. How would you physically hurt him without a vector?
