Time Slippage

This is my first creepypasta, inspired by a minor glitch when I went back to replay Pokemon Silver.

It was an average afternoon as I plugged the old cartridge into my GBA SP, wishing I could find my old Gameboy Color so I didn't have the cart awkwardly sticking out. Firing up the game, everything went normally. I chose Cyndaquil as my starter, and played for an hour or two, pausing at the pokemon center south of Violet City, near the cave that leads to Azalea Town. There I saved, and turned off the game for a bit.

The next day, I turned on the game to play some more but I noticed somehting odd. The time was the same as it was when I had turned off the game before, as though the game simply stopped keeping track of time while it was shut off. Deciding it wasn't something I needed to worry about, I kept going to Azalea town. I got to the gym and saved before going to fight Bugsy, but had to take care of something else so i turned the game off again. When I came back to it, I went ahead and fought Bugsy. But something else happened, and this time it grabbed my attention.

Somehow, in the hour or so while I was gone helping my brother, my Cyndaquil had gone from level 12 to level 15, having evolved into Quilava. And when Bugsy sent out his(her?) Metapod, its health was already half gone and it had the burn status. The same thing with Kakuna. Scyther had a little damage, but no burn status. Either way, this didn't seem right.

After the battle I went to the pokemon center like normal and healed up, before going to the west end of town. Saving before going too far so I didn't trigger the rival battle, I shut off the game then and and went to google. Wondering if anyone else had such a weird event happen. All I could find was that older carts of the game can have the internal battery die which could explain the game clock error, but nothing on the odd level up and weakened gym leader.

Turning the game back on, I was greeted to an odd sight. I know I hadn't triggered the rival battle, but when I loaded the save my rival was standing in front of me. I talked to him, but all he said was "Keep that crazy thing away from me!" before turning and running off like he normally does after the battle. Checking my pokemon, I saw that Quilava had gone up to level 19. I didn't know what was causing this, but I decided to keep playing. I continued on through the forest to Goldenrod city, where the weird got even weirder.

I approached the gym after healing up and saving outside it, by now Quilava had hit 21 and learned quick attack. Wanting to level up my other pokemon, like Pidgeotto and Geodude, I put them ahead of Quilava in the team. But when I started the first trainer battle, I saw this message "Quilava wants to battle! Go, Quilava" and Quilava popped out instead. I tried switching him out for Geodude, but each time I got the message "Quilava wants to battle!" I kept going, until I got to Whitney. I turned to head out of the gym to try and heal up, but each time I got to the door I was stopped and saw the message "Quilava doesn't want to stop" and was turned around.

Thinking I could always go back to the save outside the gym if I got KO'd, I walked over to Whitney. Once again, the message appeared and Quilava popped out. The battles with the Clefairy started off badly, with the first using Water Gun through Metronome. At this point Quilava had already taken quite a few hits, so the super effective attack brought Quilava's HP to 0. But, he didn't faint. Instead, I saw a message saying "Quilava endured the hit!" as though I'd used Endure. The rest of the battle went that way, every time Quilava got hit, the message showed up and it somehow avoided fainting.

After the battle I went to heal and save at the pokemon center. By now it was getting late, so I turned the game off. The next day, when I turned it back on, Quilava's level was the same as before, but this time it had mail. Portrait Mail, with a picture of itself and the circles replaced with the little flame that shows up for the Ember attack. The text written said "Ilovebattlingforyou Letmeburnmore" I shut the game off immediately, and put it away. I don't know what the hell's going on with this game...
