As you exit the Gym, you’ll see a Team Aqua/Magma Grunt flee off into the distance from the Devon Corp, followed by a slow-running scientist.
Heal up after the Gym, then follow the scientist, who will tell you that the Grunt took something called the Devon Parts. Okay… Anyhow, head east and follow him.
We’ll assume you visited the Route during the Optional - Route 116 & Rusturf Tunnel section; much of the extra stuff as well as Pokémon encounters is in there. In any case, when you arrive at the cave, enter.
When inside, simply go along the path and you’ll eventually find the Grunt. After a singular taunt, speak with him again to engage in battle with him. After the easy clash, you’ll regain the Devon Parts and Mr. Briney will come back and take Peeko with him to his sea shanty.
If you go west and above the ledge (below which lies grass), you’ll notice there’s a path here you can use Cut to gain access to. Do so and you’ll quickly come into battle with a schoolkid if you opt to avoid using Cut for a little while.
Continue further along and the same will let you battle another. Cut down the tree to the west after and you’ll be able to access two sets of Chesto Berries and an Ether .
From here, go south and Cut down another tree and then walk one step south and another west and press A to find a Super Potion . Now just jump off the west ledge and return to Rustboro.
Approach the Devon Corp. building west of the Pokémon Gym to return the Devon Parts to them in exchange for a Great Ball . That’s it? Cheapskates. Despite this, you’ll be taken to the top floor of the corporation to speak with their president.
The president will take your PokéNav Plus and update it with the BuzzNav , which is mostly a news notification system, sort of a mix between the Route gatehouses in Pokémon Black/White 1/2 and the Holo Caster of Pokémon X/Y.
In return, you are to take a Letter to a man named Steven - who just happens to be Mr. Stone’s son; he could’ve mentioned as much. He is currently in Dewford, which is convenient for us as we intended to go there anyhow.
In any case, finish up any business you have here and leave for Route 104 , to the south.
