Allegedly, users Paiden and TriskDaemon also had notable conversations with LabTech722. I don't think the info on the Halloweeen event can be declared complete, without the information on Gaia users to NPC interactions in the plot.

The only clue I have, is this exert of an article I took off of an extremely old Wiki-like page:
Quote:
"As Halloween 2004 continued, the LabTechs started to talk with the Gaian populace. Perhaps most notably, the ongoing relationship between LabTech247 and Whescha. These provided an extraordinary amount of depth to the NPCs, which made the eventual conclusion of the Halloween 2004 plot all the harder to handle.
During the Halloween Bash, the LabTechs talked quite a bit with users, and 247 danced with Whescha."
