Wouldn't hurt to ask what else the mods can tell us re: spiritual senses for the mission. Korra can probably help them attempt to purify the dragon, too, if it comes down to it.

Don't worry about the timing, life happens! Friday sounds good to me, and I'll definitely tag you on the jelly caves thing when you have that ready, too. Should we assume that she volunteers for the dragon mission and he fills her in on the basics while they're in the cave, maybe?
