For a Wa-san episode, it sure was good. A little history about his past and a famous shounen quote: "When you have someone to protect, you become stronger." I do kind of feel sorry for Wa-san though because he is also falling for the wrong girl with her violent tendencies that dote on Yoichi, who didn't even do anything perverted this episode, but I guess he has his own "good" reasons for those feelings.
