well the whole pool singing and dancing thing was a homage to key Metal Idol or something like that one of those random idol shows did the same crap. Overall not a great episode unless all you want is fan service but on the bright side it finally gets us into a spot where they can start in on the more serious part of the plot if they so choose in the future. I'm still amused by this show and at this point I think we just need to get over what its not and go with what it is. Another season has been confirmed and chances are this one will be mostly girl introduction with next season taking on the more serious plot aspects. Its a shame as they should easily be able to handle both at once but its still what we get and I enjoy a few of these relatively mindless comedy/romance anime's in between all of the over serious series.
