Pokemon X: Santalune Gym

This is Part 3 of my Pokémon X guide. It details Santalune City, Route 22, and the Santalune Gym. If you are not at this point yet, please refer to part 2.

Once in Santalune City, the Pokemon Center is straight ahead of you, and it should probably be your very first stop. Tierno will come in after you and explain everything. The Pokemon Center counter is directly in front of you, with the PC beside it. If you get a Mystery Gift, the delivery woman stands on the other side of the counter. The room to the right of the desk is the Pokemart. The room on the left is the dressing room, where you can change your clothes.
At this particular Pokemart, the man on the left is selling Pokeballs and Potions, while the man on the right is selling X Attacks, Dire Hits, etc.

Now then, there's plenty to do in the city. Next door to the Pokemon Center, you'll find the Santalune Boutique. There's a variety of hats that you can buy here, and put on at the Pokemon Center. Feel free to try stuff on, and buy what you like. Don't spend all your money here though, there's plenty more Boutiques throughout Kalos!
Heading left from the Pokemon Center (past the plaza), you'll find two houses. The one of the right has a woman who will check how much your lead Pokemon likes you. The house on the left has a girl who will tell you about all the Kalos Gym Badges. Heading right and into the plaza, you'll see a large Roselia fountain. To the right, you'll find a house. Inside is a boy who will give you a Great Ball. To the left of the fountain is another house. This one has a Hiker inside who will trade his Farfetch'd for your Bunnelby. If you have a spare Bunnelby, this trade is great, especially since Farfetch'd is pretty effective against Viola.
If you head straight from the Roselia fountain, you'll find the Trainer's School. The teacher in there will give you X Attacks, and X Defenses. There's nothing to the left of the school yet, but if you head to the right, you can find the Gym. Blocking the door is a Roller Skater, who will give you a pair if you can beat her in a battle. She uses a Level 7 Zigzagoon.
Roller Skates are great. If you move using the Circle Pad, you automatically use them. This is sometimes not the best thing, if you need to move more precisely, but that's what the Control Pad is for! They'll probably feel a little clumsy at first, but you'll get used to them soon.

Before you head into the Gym, I recommend checking out Route 22, which is directly to the right of the Gym. Leveling is always good! Here, you'll find a Rising Star with a Level 6 Psyduck and a Level 7 Litleo. Just past her is a Lass with a Level 6 Goldeen and a Level 6 Marill. If you managed to get a Pikachu, she's a great trainer to practice with! In the grassy patch behind them is an item, but you can't get it until you can use Cut. Further down the path is a male Rising Star with a Level 9 Riolu. Even further down the path, you'll find a Schoolgirl with a Level 8 Bunnelby. Just past her is a Lass with a Level 8 Flabébé. Despite what it looks like, Flebébé is a pure Fairy type Pokemon, and does not become part Grass upon evolution. Up the nearby stairs is actually the Pokemon League. You obviously cannot enter yet, and you also cannot enter the other side of Route 22. So, instead, jump over the cliffs near the Lass until you get the Super Potion.
You can also catch Bidoof, Bunnelby, Psyduck, and Litleo here.
Train here for a while, as you probably cannot beat Viola with Flying-type moves alone. You'll need something else as backup for her Vivillon.

When you feel ready, you can challenge the Gym! Make sure you bring plenty of Potions with you, as I haven't found a way to get out of the Gym until you beat the Leader! The Gym, at first, looks like a museum. But if you jump onto the nearby pole, you'll drop down onto a large spider web coated with dew. Just follow the little dew bubbles to the Gym Leader. You should probably make little turns over to the trainers though. Just for training.
The first Youngster has a Level 10 Ledyba. The second Youngster has a level 10 Spewpa. The Lass right near Viola has a Level 7 Kakuna and a Level 9 Combee. Your last foe is Viola herself, so make sure that you heal your Pokemon first!

Viola has a Level 10 Surskit and a Level 12 Vivillon.
Surskit can be pretty rough on those expecting to blast through the Gym with Fennekin. While her Vivillon knows the new move, Infestation, which is basically like a Bug-type Wrap or Fire Spin.

For defeating Viola, she'll give you the Bug Badge and TM83 Infestation. The back of the tent behind her will open up, allowing you to go up some stairs and into the entrance of the Gym. The man waiting in the entrance will tell you to go see Prof. Sycamore in Lumiose City. You can start making your way there if you go left from the Trainer's School. Go up as well, instead of just going straight left. You'll be greeted by Alexa, Viola's older sister. She gives you the Exp Share. This Exp Share is not like the one from other games. It is a Key Item, and effects your entire team! Keeping this on at all times makes it much easier to level your Pokemon and keep them all within competitive levels!
