Because Jiminy Cricket, another fella who had followed Sora on his journeys, had a notebook. This notebook was completely empty when Naminé was done with her memory-repairs... or so we thought.

It turns out Jiminy found a message he hadn't written, and in order to investigate I digitized the notebook to examine it in greater detail. What we found was... incredible.

Naminé had left a message in the notebook, that me and a Sora made from the data inside the notebook had to traverse through the notebook in order to figure out. The message in question was that Ansem had hidden the research data he had compiled inside Soras heart...

And the nature of that data, is the key to freeing you, Terra, Ventus, Roxas, Xion, Naminé... everyone connected to Sora. To give them a second chance.

[Hem oves closer to her, and takes her hand in support.]

To bring all of you back... Aqua.
