“Stone Skipping,” aka the obligatory beach episode, continues FLCL: Progressive’s trend of mysterious metaphors and unfinished sentences, giving us plenty to think about moving forward. It’s a much slower starter than the previous few episodes, but does end on one of Progressive’s most intriguing scenes yet which shows our unlikely hero Ide finally taking on a life of his own.
With an assumed truce between Jinyu and Haruko, the two tag along on the student’s beach trip, which Haruko sees as a perfect excuse to flirt with Ide and the boys. Luckily Progressive doesn’t milk the fanservice too much before moving onto the next plot point where we meet Mori’s girlfriend Aiko (and her emotional support plant). The group cycles through various beach festivities in what amounts to a pretty harmless but boring montage. Again, a slow start which doesn’t suit FLCL well.
