As you head into Courmarine City you'll receive a Holo Clip. Your rival will challenge you to a battle in front of the gym. Feel free to prepare up and head over there whenever you want to. Let's explore the current area first though.
Head east until you see a house. Head inside and talk with the old man there. He'll give you a Silk Scarf . Awesome. Head back outside and talk with the man at the nearby red stall. You'll be able to see his wares.
Courmarine City Incense Shop
Once you're done, look at the blue stall just below the red one. You'll see that you're able to take a berry from the counter. Feel free to. The berry gets replaced each day and the berry is random. You can give a tip if you so wish to. Now turn on your Dowsing Machine and find the nearby Awakening .
From here, head east and speak with the Fisherman when you see him. He'll give you a Good Rod . Yay! Follow the path. When you see the building to your east, it's the Seaside Station that's used to reach the Pokémon Center and Courmarine City Gym.
There's a little more to do around here though. Head north from the station until you reach the hotel. Head on inside. If you're friendly enough with your Pokémon, talk to the woman sitting down at a table by the western wall of the ground floor. She'll give you a Lucky Egg if you are.
Head upstairs and to the last room to talk with the Game Director. As your Pokédex gets more and more full, speak with him. Once you're done; head outside.
Tip #032: You Feeling Lucky?
Well you should do after netting yourself a Lucky Egg ! This awesome item boosts a Pokemon's gained experience by 2/3 when held. Previously you had to steal it from Chanseys, who were super-rare and the Lucky Egg itself was super-rare too - definitely not the best of combinations. Thank heavens it's so easy to find one nowadays!
Follow the path west until you find the woman looking out at the ocean. She'll ask you a random question, telling you a description of a move. Respond with the correct move and you'll receive the TM for that move. You can do this once a day until you have all TMs. The TMs you can get are as follows:
- TM62 - Acrobatics (does more damage if no item held)
- TM63 - Embargo (prevents the use of items)
- TM92 - Trick Room (slower Pokemon move first)
- TM100 - Confide (reduces the opponent's Special Attack)
Once you're done with her, head to Seaside Station. As you head into the Seaside Station you'll bump into Sycamore. He'll talk about Mega Evolution then give you HM02 - Fly! This super-useful HM lets you instantly warp to any visited town or city, although you'll need to beat this town's gym leader to earn the rights of usage.
The famous actress will also mention that she wants to battle you the next time the two of you meet. Oooh. Now talk to the woman at the counter if you want to ride the monorail. Hop on and you'll arrive at the next station, Hillcrest Station.
Talk with the man wandering around here to receive a Metronome . Head west and you'll find the Pokémon Center. Head on in and heal up as well as checking out stock.
Courmarine City Pokemart (Right Clerk)
Head to the west side of the center and you'll find Mr. Bonding once more. This time he'll give you a Befriending Power . Head outside and stand to the west of the house to the west of the center. Use your Dowsing Machine here and you'll be able to find a Max Repel .
Once you have it, head west to the junction. Take the path leading south. When you see a path leading back east, take it. Enter the second house. Talking with the man with purple hair will allow you to change the current background music. You can tip him afterwards if you want.
Talk with the girl in the back right corner of the house. She'll mimic the sound of one of your party Pokemon. After she does, correctly tell her which Pokemon it was and she'll give you a Poké Toy as a reward. If you fail you can simply retry however.
Once done, walk back outside. Head back to the path going south-north. Head south to the gate. Talk with the man with the black jacket inside to receive a Black Sludge . Wonderful. You can now head south out of this gate into Route 13 - Lumiose Badlands if you wish to. If you do then skip ahead to that section. If not; then continue reading.
Head back north out of the gate and continue north. Keep going north until you see the path leading east just before the Pokemon gym. When you do so it, follow it around to the lookout. You'll find a Sky Plate here.
Head back to where the path lead off. If you go north here, you'll enter the gym. Remember; your rival wanted to battle outside of it, so if you try to enter they'll appear and the battle will begin. Make sure you're ready then try and enter. Let the rival battle begin!

If Chespin was your starter
If Fennekin was your starter
If Froakie was your starter
Once he or she's defeated; head back to the Pokemon Center. Heal up; then stock up and head back to the gym. It's time to take them on!
