Xion said Riku saved her but he saved her from what exactly? The previous scenes, Xion was at Castle Oblivion searching for the truth about herself (https://www.youtube.com/watch?v=Bh5OsgIz4Zo#t=5537). 1:32:17
Her next reappearance is when she, Roxas, and past Riku are having some sort of "headache" issue at Destiny Islands (https://www.youtube.com/watch?v=Bh5OsgIz4Zo#t=5611). I'm guessing that's when Sora's memory was in the process of restoration? 1:33:31
Namine in the next scene tells Riku that Sora's awakening would be greatly delayed because of Xion's and Roxas' existence (https://www.youtube.com/watch?v=Bh5OsgIz4Zo#t=5747). The Riku/Namine scene is a flashback I think. 1:35:47
So I am not too sure what Riku saved Xion from exactly but I think maybe Xion (and Roxas?) were about to be erased from existence but Riku intervened and stopped the memory restoration? (https://www.youtube.com/watch?v=Bh5OsgIz4Zo#t=6831) 1:53:51
Riku knew that erasing Xion and Roxas was the quickest way to awake Sora because that's what Namine told him in the flashback scene. Riku, desperate and at times ruthless, in his quest to awake Sora chose to delay the awakening. Riku was a lot nicer to Xion than Roxas lol. He gave Xion a chance to think it over.
So is this what Riku saved Xion from or was it something else? Did he save Xion from being wiped out of existence in that moment? I am just very curious..
