[Jack Simth]

Are you referring to my mentioning that Jason didn't get any XP last session? If so, mostly it's so I have a record of it. Also helps me keep track of how far ahead or behind the characters that don't spend XP are from Jason, in case someone asks.

Are you referring to the conversations NPC's have with each other? If so, well, it's part of a DM's job.

Are you referring to the little whispers I make to myself during the gaming session? If so, it serves a couple of purposes; someone who checks can then note that I'm not just being arbitrary on what works and what doesn't (such as the scrying attempt on the Ghost, or Derrel's Detect Evil vs. the possesed critter), to make little notes to myself in case I read through the log later looking for things I can build off of or to make sure I'm not accidentally cheating the party on the mechanics, and to roll dice that the party wouldn't know about (a handful of Jason's Rejuvination delays, for instance, or the variations in mass production on those Necklaces of Adaptation picked up at the Mine).
