Learning Sprout Tower's Pokémondō in Pokémon Silver (Part 4)

After beating Falkner, I decide to take in the scenery. One important feature in Violet City is a pagoda named Sprout Tower, a place where sages study the Way of Pokémon. I eventually best the mighty Sage Li, and he gives me the technique for Flash. With Flash in hand, I can now make my way ti Azalea Town.
