What could have gone wrong...(dn)

Now, everyone who is familiar with Death Note either knows or will soon about the Xantos Roulette of Light's that leads up to That Which Shall Not Be Spoiled. In the series itself, this plan worked out without a hitch. Almost suspiciously so. So, between me and saint_archie, we came up with a list of places that it could have gone wrong. (If nothing else, slowed it down quite a bit.)

Credit for these is split between Arch and I. Some of them have commentary, some don't. And all are, of course, spoilerific
