Basically, the whole Zacharie thing started off as an OFF reference in RP. I didn't even really get to RP with him though. Then, I started to like the Zacharie thing everywhere a lot. So I kept it.
Permanantley.
When I'm Zacharie, I'm not always OFF Zacharie, though. In the normal chatrooms it's just me with the name Zacharie. In RPs sometimes I'll RP asm me with the name Zacharie, too. Also sometimes in RPs I'll be an OC Zachrie. I have a lot, and generally they are just mixtures of other characters (and people), like Rory+Cry Zacharie, Cry Zacharie, or Misha Zacharie.
