Card Captor Sakura - episode 63

Sakura and her gang are at a water park, suggesting to the audience that it's summer in Reedington. Except that it's not Reedington because this episode wasn't originally available as a united states or canadian dud. This means that I had to watch the alternative dub of this, which is a version closer to  the original, which comprises of several differences from the version where the characters and locales are given westernised names. Here, their local town is Tomoeda, and all of the characters, apart from Sakura and Kero, are named differently. Onward with the episode, one of Sakura's friends is having difficulties with her locomotion in a body of water. She is unable to even stay afloat, quickly sinking despite the human body having positive buoyancy.

There is one flaming point of light in her life though: Sakura. As her fellow student and friend, the main character teaches her to swim and the lesson goes without a hitch. The learnt ability turns out to be solid gold. The water of the premises start reacting to Ariel's (Eli, in this version that's how he's named) command and soon the bathers find themselves in need of vacating the pool. Sakura's friend is the last one behind, but since she's no longer helpless in the water, she eventually swims her way to safety. All is well in the end, while ruby questions Ariel/Eli about his methods of testing Sakura's spunk and problem solving skills. The leading protagonist assures her in a way that implies that he wouldn't let anyone come to harm if Sakura's timely intervention proved not to be enough, but the episode doesn't give away that card, leaving it up to the viewer to assume the goodness in the dark-clad kid.
