[X] Train with Dratini and Pineco - Both of your Pokemon are good in a battle, Dratini having grown through their playdates, and Pineco being rather perceptive herself. Training for a few days would help them grow.
[X] Travel to Cerulean City - Home to Kanto's water-type gym run by Misty, the city has several attractions such as a massive bike store and Cerulean Cave. (Free if chosen this turn and you don't face the Fighting Dojo)
[X] Call Tetsuya - An old childhood friend of yours, the two of you drifted off recently. He did say he was headed towards Pewter City through the mountains.
