*thunder*
Ash woke up gasping for air, and sweating, like he just woke up from a nightmare, but he couldn't remember what it was about, or of it was nightmare at all. Unfortunately, his headache wasn't helping, and neither was the storm outside.
Out of reflex, Ash reached out to the light switch, and turned the lights on. He looked around, and saw that he was back in his room. The room was as messy as he remembered, but he also noticed that it was different from what he remembered.
"My head," groaned a feminine voice.
Ash looked at the source of the voice, and saw Celebi, however, this one was different from the one he remembered. This one was larger, not by much though, and she had a rather pear-shaped figure. He assumed this one was female due to her small breasts, and wide hips.
Before Ash could say anything, he recalled the information about anthro evolution, and its different classifications, which allowed him to classify Celebi as a Type 2 in the Anthro Evolution Scale. At the same time, he also remembered the lessons in which he learned about this particular information, and some other random bits of memories.
"Oh, I hate how this new world affects my body," said Celebi to herself as she stood up, and shook her head. She looked at the bed, and saw Ash holding his head. She climbed on the bed, and said, "Ash! Look at me!"
Ash opened his eyes, and looked into Celebi's blue eyes.
"Deep breathes… that's it. Slow down… focus on my voice," said Celebi as she placed her hands on Ash's cheeks, and looked into his brown eyes. She watched as Arceus' Chosen One slowly calmed down, then she smiled, and asked, "Try to focus on the last thing you remember from your original timeline."
"I… I…" stuttered Ash trying to separate his memories from his original timeline from the ones of this timeline.
Celebi waited patiently as Ash struggled to make sense of his confusing memories, and she couldn't rely on her memory because of how she experienced time in a nonlinear manner due to how she lived. This wasn't the first time she traveled with the mind of another through spacetime, but it didn't make the process any easier for those who were not used to traveling through the spacetime continuum. However, there was no other way to save Ash from his collapsing timeline, and place his mind in the new timeline.
Ash managed to sort through most of the mess that was his memories at the moment, and managed to find his last memory from the previous timeline.
