You scour news sites for information. You don't find anything of note beyond what you've already heard. A few sites noticed the strange burning on the partially sunken battleship but nothing more.

As you storm off through the gym, you get a tad lost. You were in the back area that was normally off limits to the general public, and the layout wasn't intuitive. It takes a good 10 minutes to reach the main battle arena (still empty and plain) and then the main entrance. As you stomp towards it, you feel something tug at your pant leg. A small pokemon about waist high had grabbed your pants and was tugging gently. The yellow and black pokemon, with freakishly long hair stared up at you with big mournful eyes, pleading.

If I'd hazard a guess, I'd say you did. You put a large portion of Devon out of business and they won't bounce back any time soon. Not without pirating some Silph ships first! Byron boomed laughter, thoroughly amusing himself. But thats just me. You did destroy most of a major city Devon had strong economic activity in.
