Vanilla = original; referring to the non-Final Mix versions.
Gotcha.
See I am confused myself because the report that I quoted which vaguely mentioned Kairi was called Ansem's Report 11 but the first of the 'Secret Reports' which I'd found listed at the DestinyIslands.com link was also called Ansem's Report 11 but pertained to events from Days and the one mentioning Kairi was not there at all(I'd quoted it from a different source). So I'm thinking DestinyIslands.com messed something up or I don't know...
