I actually went ahead and watched that episode. Thoughts were:
- Makoto is, on her first try, good enough at ice skating to compete internationally. Reincarnation FTW.
- In the time since this episode was aired, we've actually observed craters filled with ice on the Moon.
- Canonically Sailor Moon's boots can turn themselves into ice skates. Can anyone think of an application of this when combined with Sailor Moon Kick?
