I found this to be a very refreshing first chapter.
While the Professor did run out of Pokemon as is the norm for most fics, he found an unlabeled egg to give to Danny instead! I must say I couldn't see that one coming. One thing I can't help but wonder: since when was there Raticates on Route 101? Or did that just come from the Ratatta thing? Meh, just a nit-picky thing I do.
Otherwise, this is a fantastic opening. I can't wait for the next chapter!
