Ah, sorry, didn't realize that that one would need a specific parallel. I could bullshit one up but it'd be too much of a stretch. Can I change it to the time he saw the castle of Hollow Bastion on the projector in Deep Jungle? He recognized it because Kairi had been there, and she had been told that story several times at that castle. Since her heart had been in Sora's, he had subconscious access to her memories, so he found the castle familiar.

If that's still too much of a stretch, it can just be straight up him remembering being told that exact same story because of the same heart connection. (i.e. He hadn't actually been told the story, but he remembers it because Kairi's heart was inside his own heart and she remembered hearing it.)

If that's still too much of a stretch i have like a zillion more ideas nbdnbd
