!Plot

[[WMG: The ones who really saved Arakawa from Ric's dad.]]
Since we know that while the residents are [[{{Cloudcuckoolander}} Cloudcuckoolanders]], some of them are [[CrouchingMoronHiddenBadass more capable then they appear]]...

The [[http://www.mangafox.com/manga/arakawa_under_the_bridge/v04/c100/28.html facial expression and hair on the bottom-left]] is just so Kappa. And [[http://www.mangafox.com/manga/arakawa_under_the_bridge/v04/c100/29.html the man in the yukata]], can that be Billy? Although, [[http://www.mangafox.com/manga/arakawa_under_the_bridge/v06/c139/3.html his facial features]] seems more [[http://www.mangafox.com/manga/arakawa_under_the_bridge/v06/c159/4.html Whitey-like]].
** Thanks to Episode 6 of Season 2, we know that [[spoiler: the Mayor apparently has a lot of clout to throw around. He's also apparently Nino's guardian.]]

[[WMG: Everything and everyone under the bridge only exists in Nino's mind]]

Given various hints dropped in the anime, it seems to be implied that Nino is schizophrenic and Ric, Sister, and everyone else exists in her mind, and she just lives under a normal bridge.
