Kingdom Hearts II Where did Mickey and Kairi come from?

After seeing the post in the KH1-forum about Kairi's "disapperance" during the Rikunorth VS Sora fight in Hollow Bastion I remembered something that's been bothering me in KH2.
When the party goes into Kingdom hearts at the end, the door closes right in front of Mickey and Kairi, leaving them outside.
Later, after fighting Xemnas for the first/second time they're back with Sora and Riku....how did they get there?

 

Wasn't it Sora & Riku that went back to them after the battle? They were at the place that led to the Door.

 

^Yeah it was Sora and Riku that went back. Mickey and Kairi just stayed there.

 

If thats true Kitty then Sora, Riku, Donald and Goofy teleported to that location or kingomd hearts spat them out.

 

Yeah... I think they were still inside Kingdom Hearts,seeing as they were all talking about how to get back. If they were back at the platform by the door they could have just walked down the stairs instead of going trhough a dark portal.

 

No, cuz the castle was packed with Heartless, remember? Maleficent an Pete gained you some time by staying behind and fight them, but I'm sure they didn't kill them all. There were thousands of them.
They were at the platform/tower thing. Then Xemnas Dragon attacked, and you know the rest..

 

That would be my guess.

No, they were outside at the place that lead to Kingdom Hearts. Plus the place started to collapse so they couldn't walk down.

 

K. I checked the video. It's the same spot. still weird how they suddenly got there though.....but that may well be another mystery of the Kingdom Hearts..

 

They probably teleported because Kingdom Hearts knew they had defeated Xemnas (not really) and they got teleported out of the weird Castle thing when Xemnas Armour was destroyed or it wanted to seal itself if Xemnas would come back, but it is weird as they couldn't of walked back because Sora jumped to this Castle where Armour Xemnas was so there must be a teleport thing or something.

 

Well Mickey is really powerful and I think he might be able to teleport there, and Kairi is one of the 7 princesses so she would have some power.
