an obvious set-up for future Kira plot developments.
THIS!!! A HUNDRED TIMES THIS!!!!!!
I've mentioned this before, but this novel is basicly RBoE, it's a setup for more. It's like a two-parter on the tv-shows. Part 1 might not impress or make a lot of sense. But watching both episodes back to back, things become clear. I have a feeling that a lot of the things set in the 'past' will make much more sense when this story is continued/concluded.
