>>9492263>Why was she slapping him
Misty slaps him because she sees Pikachu in a really weak state, and asks "How could you put it in such a condition?!", or something like that.
I have no idea where the subs are coming from in that screen cap. The only thing Satoshi is saying is "thank you" for being worried about him, because when she runs over to him worried about Pikachu, he thinks she's worried about him.>did her beat the shit out of her in retaliation?
No. He gets depressed and asks himself if it's his fault that Pikachu is weak.
