Go east from the door of Professor Magnolia's house to find a narrow passage around the back of the house. Follow it to the end to find TM57 Payback.
Go back to the front of the house and go west through the garden path to find a Great Ball.
Go south from there until you can't go farther south, then go east along the garden wall and check on the sparkle to find a bottle of Fresh Water.
Go outside and go south. After some brief dialogue from Hop, go south to return to Wedgehurst. In Wedgehurst, you will see Hop go into the station. Go to the entrance of the station and Hop will give you TM40 Swift. You can use TMs to teach moves to your pokémon, and you can use them as many times as you wish.
Go into the station and there will be a cutscene. You will get a set of Camping Gear.
In the station, talk to the people to the left of the turnstiles, and if you have save data from Pokémon Let's Go Eevee, you will get an Eevee, and if you have save data from Pokémon Let's Go Pikachu, you will get a Pikachu.
Talk to the backpacker near the exit of the station to get 5 Poké Dolls.
Go outside and you will reach the Wild Area.
