After giving Gengar the recipes, Heath left with Cynthia. However, this trip to Petalburg Woods had been too short. He had finished everything in just a few days, so Heath's Food Truck's teleportation function was still on cooldown, which he found rather unfortunate. He now faced a few choices: either stay in Petalburg City and run his food truck for a while until the teleportation cooldown ended, or drive the food truck onto a ship and sail back to the Kanto Region, going straight to Cinnabar Island along the way.
However, after looking up the distance and travel time from Petalburg City to Cinnabar Island, Heath felt that simply waiting a while seemed better. After all, the journey back to Cinnabar Island would take enough time for his teleportation function to recover anyway. Besides, traveling by ship was honestly rather torturous-at least, that was how Heath felt. Rather than take a ship, he might as well wait for the teleportation cooldown.
Heath got a little seasick. Although he did not particularly want to admit it, he really did suffer from seasickness. The rougher the waves, the worse it became, and there was nothing he could do about it. That dizzy, spinning sensation was unpleasant, and he could not stand it himself, so he simply chose to stay in Petalburg City and wait out the cooldown.
And so Heath drove the food truck straight to Petalburg City. Cynthia, however, had to head back. After all, she was the Sinnoh Region's Champion, and being able to slack off for a few days was already pretty good. If she stayed away any longer, the Sinnoh League would probably go crazy. Heath very much wanted to keep developing his relationship with Cynthia, since he felt they seemed ready to take another step forward, but
