The End of Uselessness?

Who would believe that Maruo on Tokyo Dogs is actually ending his streak of uselessness?  Not that he was totally useless before, but he certainly didn't do a lot aside from hitting on ladies and believing in people.

Well, he's still up to his old tricks--but now he's also busting gambling rings all by himself, going undercover, and even saving Detective So.  Oh my God, how did that happen?  (Granted, Det. So only needed saving for like 30 seconds and could totally have gotten himself out of it...but he didn't!)

As if all that weren't enough, Maruo's adamant belief in other people proved to be more than just another stereotypical element of Japanese storytelling.  It actually 1. helped solve a blackmailing case and 2. infected Det. So to the point that he was unnecessarily nice to two whole people.  Holy crap.

PS:  Guess who wore a suit for a good three-quarters of an episode?  The tables have turned, my friends.
