The player first has access to Ametrine City after defeating the PULSE Avalugg inside Ametrine Mountain. After meeting up with Shelly, she will look around the city for news about Heather. During the inspection, the player will meet Blake for the first time.
When Blake knows that the player has the Ruby Ring, he will steal away the ring and escape to the mountains. The player will have to solve the puzzle inside his apartment in order to rescue Heather then later team up with Cal and Shelly to chase Blake.
When the player and Shelly inspect the city, they will come across an abandoned house. Inside is a beta version of a PULSE machine and a diary that belongs to one of the house's owners.
Now Mama has gotten very sick too...
We moved to Ametrine to get away from the polluted city, but the doctor says it may already be too late. I don't want her to leave me like papa did... Please, please, please don't let her go...
Mama is with Papa now after all. Evelynn and I are all alone now... She's doing her best to take care of us, and the city is helping as much as they can, but it's still really tough...
I don't want to be alone...
I have bad news...
Evelynn called the doctor...and he says that I've developed the same disease that mama had...
We knew it ran in the family, but nobody thought it would happen so soon...
Diary, I'm really scared...
The doctor says I still have at least a few years...but I don't want to die that young....
I don't want to go... I'm not ready to face Mama and Papa yet...
I feel so guilty. Evelynn has been worried sick about me...
She's been staying up all night, always reading and researching to see if there's anything that could be a cure.
I'm really glad that she cares about me so much but I don't want her to push herself too
far. What if she gets sick too?
Maybe it would be better if I died sooner. I would be less of a burden on Eve that way...
Evelynn has been working herself to the bone... She's building some kind of machine that she says will enhance the healing powers of Pokémon.
She says that if she can amplify her Pokémon's healing potential, maybe it could cure my disease too.
Eve has always been really smart, but if something like that is possible...I would be so happy!
If anyone can do it, she can. I'm so afraid to hope, but I can't help it.
Maybe I have a chance after all. Maybe I'll be writing to you for a very long time, Diary.
I'm scared. Today, a man dressed in black showed up at our house. He said that he had heard of the machine my sister was making, and he wanted to use it for his organization...
Evelynn was going to refuse, but... I'm so stupid... I got in the way and he used me as a
hostage against her...
Now poor Evelynn has to do whatever he says otherwise he says he'll kill me.
Why is it that every time I hope things can be okay, they go horribly wrong?
The handwriting changes and appears unsteady after this entry
I'm sorry. This is going to be my last entry.
It's really, really bizarre, but there was an accident with Eve's machine.
She was applying the finishing touches for a test run and something went wrong.
Because of the machine's energy, the Magneton she was testing it on accidentally evolved during the test... and then because of the evolution the machine went haywire...
Oh... did you know, Diary, that when Magneton evolves, its three parts fuse into one?
...I don't know how it happened, but...the machine transferred that energy into everyone who was nearby...And when Magneton emerged a Magnezone...
I was looking at my own body...Like it was a mirror or something...
And I could hear Eve's voice and that man's voice, and they wouldn't stop. They still don't stop. It seems... the machine's energy accidentally fused the three of our consciousness's into one body.
I don't know what's going to happen to Evelynn and I-- our bodies, that is...They might die without us...
But it seems that we're going to have to leave... I hate this. I hate this so much... But it's stupid.
