the letter is not simple
[Q. In the last scene in the ending, they received a letter from the king. I'm quite curious to what's written in it.
A. I was troubled for a very long time on whether I should show the letter's contents or not, and in the end I decided to let people speculate it themselves. You can guess what's in the letter by looking at those three's facial expressions: Sora looking at it blankly, Riku smirking and Kairi looking slightly worried. If it was just a "Hello, it's been awhile", they would be smiling instead so at least it's hinted it is not that kind of simple letter. Actually, it was planned to have a little more scene to it and by watching it you could tell what's in the letter. I might be able to show that scene when I get the chance to. /QUOTE]
and yes, they did get the letter at the end of kh1
what sounds more likely?
option 1: sora cuaght pluto and read the letter
option 2: pluto outran sora(who can use glide) and then got to the ocean. he then rolled the letter up, using his paws, put it in the bottle(again, with paws) then put in the cork, let it float, and it made it to DI after an entire year of floating around.
I got one.
Sora didn't cath pluto because he got distracted when he saw that Org member who pointed to Castle Oblivion. SO Mickey probably sent it again.
If it was something VERY important, Mickey would've told Sora and Co. when he saw them for the first time in "Hollow Bastion"
DOn't you think?
Maybe the letter is all
"hey, Sora, now that this is all over, I want to share the legend of the keyblade with you. You see, long ago......."
Something of that nature.
