Y-Locke's Log: Day 3

Today, there was another delivery girl in the Pokémon Center, this one in red, with a Discount Coupon for me.  The blue-clad delivery girl was there again, too, and gave me a level 12 Vivillon, giving me a full party of 6. 
I began my exploration in the traditional manner, by walking into random people's houses.  One of them taught me about evolution cancellation, though I don't foresee myself making much use of it.  Another, though, gave me a Great Ball, which will come in really handy. 
I found the Trainers' School, where someone gave me some X Attacks & X Defenses to help me on my journey. 
I went to the local gym, but someone was standing before the door.  She offered me rollerskates, strangely enough, but only in exchange for a battle, so I obliged her.  Her Zigzagoon was much higher level than Theodore, so I let my Torchic give it a go.  Two moves later, and Roller Skater Rinka was defeated, and Theodore had learned Growl.  
I spotted a path east of the gym, and gave it a look.  I was promptly challenged to battle.  I used a Potion to keep Theodore up against a Scratch-happy Psyduck, but we eventually prevailed against it.  By the time that the opponent sent out Litleo, though, I was ready to switch out to Sly.  It wasn't exactly easy, but Sly did manage to level up, learning Howl in the process. 
I retreated to the Pokémon Center, but I realized that this route would likely be good training for the gym. 
Right past that first trainer, though, I found some grass, and so I went in to see who might be joining us.  It turned out to be an Azurill, my first Fairy-type.  Since he's a mouse who's blue, like water, I named him Mousea. 
Since I already had a full party, Mousea got sent to the PC box, but I retrieved him when I returned to heal, leaving Vivillon in his place. 
Seeking to test their muster, I went to the next trainer on Route 22.  The Lass struck hard and fast with a Goldeen, and I wound up swapping out Theodore for Mousea.  Unfortunately, his only damaging attack was Water Gun, so I sent out Orion to finish her off.  I put Mousea back out when she sent out a Marill, but I wound up switching back to Orion, anyway.  All three leveled up, though, and Mousea even got a Bubble attack to replace its otherwise-useless Splash. 
I faced one more trainer, with a Riolu, and yikes!  That thing was level 9.  I swapped out Pyrrhini for Orion, and just in time, I suspect.  Riolu's Quick Attack hit hard.  Well, at least Pyrrhini leveled up and learned Lick, which I expect will be very handy, indeed. 
Having retreated to the Pokémon Center after each battle, I decided to lead with Sly for one last match.  It ended up being against a schoolgirl named Mackenzie, who had only a Bunnelby, but it put up an unexpectedly good fight.  I managed to defeat it with only Sly, though, and no items. 
After returning to the Pokémon Center, I decided to call it a night.  The gym could wait for another day.
