It's Yua's dream to sing but the memory of her freezing up on stage stops her from pursuing her dream. Yua gives up on this dream when they run into Lulu...Amu gets into a battle with Yua - there's a reason why she can't sing in public.
By the looks of it she could be a runner and a hurdler too. Did you see how fast she sprinted up that hill and that jump she did!? It was cool but at the same time I was thinking "what the eff?" This has to be one of my favorite eps so far
This episode gave me a vibe of a final episode of a series even though it was obviously not. It was probably because of the two-part episodes and song without the usual background picture ending.
