I'll give you that the effect of pulling out at the end of a song is a standard trope.



But while there's no way of knowing whether it was intentional that on the two key bookends of a running season plot, that the same pull-out from the same location (granted, reusing Flash resources) is rather an interesting curiosity and one you have to wonder if done purposely.



It might be nothing at all, as well. I just found it interesting after rewatching Crystal Empire recently, post MMC.
