It is south of i think dewford it is called metiorite falls. Go up the water fall and go through the cave you'll find steven and you and him can batlle. good luck
steven is in Dewford cave, when you give him the letter, in return he will give you the TM steel wing. when you go through dewford cave it is easier to get the HM flash first hope i helped :)
If you walk above Dewford, staying on the beach, to the left will be a cave entrance. Explore the cave and eventually you will come to a room where Steven is. The cave is dark so you may need flash to help light the way. Hope this helped!
You find him in the cave at Dewford first on the 4th floor. You should use flash. To get flash youu speak to the hiker when you first enter the cave. But before that beat Brawly. Then you can use it. hope i helped JIMMYL Answer Improved by cristiegdoe5
he will go to the cave of dewford that you give steven a letter from Devon corp. f68bin
you go to the end of that cave in the north and he also gives you TM steel wing.
Go on the old guys boat and go to Dewford. Go the the Granite cave and get the Flash from the hiker. Teach it to a Pokemon and wander around the cave until you find Steven.
In Dewford at the cave, Not hard to find.
u give him the letter in the cave in dewford...u wuld need flash..

it's not in dewford cave, it's in the sealed chamber.
First talk to the Hiker Guy in the Cave and teach your stater Pokemon flash then keep going down then go up and you'll see Steven!
