Awhh.. Satoshi hit the sunglasses guy! xD
Okay, in the pannel where Satoshi smacks the sunglasses guy, he's not punching him, he's more like slapping him. This is very important because it tells you about his character. He's gentle.. and more of a pretty boy than a tough guy. xD Yup.

And also, the objects in the last pannel are knives, sticking into a surface. I know it's hard to tell, sorry. x3
