Despite how agonizingly slow it was - an emotion Lex only felt because he wanted to hurry up and complete the changes with the system - surveying so many people was actually quite entertaining.
The process actually took several days, and they surveyed over ten thousand guests, workers and general inhabitants of the Inn. It was good to see so many old faces once more - faces Lex expected to see more often from now on that his attention had returned to the Inn.
Yes, this was just a list of some of the beings surveyed, and in no way a reminder of characters long forgotten with their storylines- eh, with their personal issues unresolved. Why would Lex require such a thing? As an immortal now, his memory was perfect.
