Hm, I wonder. If you destroy the source version of something, do you not destroy all its reflections?

Likewise, what happens if your reflection isn't on a Shard when it rejoins? What if your reflections travel to the Source? What if they manually rejoin you while the corresponding shard is still intact, much like Ardbert did? What happened to the reflections on the 13th - were they destroyed, or do they all have analogues in angry Voidsent (i.e. who does the Cloud of Darkness and Diabolos correspond to then?)
