Votun was walking through route 30 defeating lower leveled pokemon with one hit from his Dratini. He thought to himself (Hmm, this Dratini must be higher than the regualr starter to be winning so easily, too bad I can't catch anything though...)
After leaving 30, Votun came upon route 31 and basically repeated what he did before. "Nothing special about raising a dragon team at this time.." he said to himself as he came upon Violet city.
