When the guys get to Wolcott’s place, everyone is immediately creeped out except for Sheldon.
Once inside, everything Wolcott says, and much of what they see inside, only validates the fact that he’s a bit unstable.
After he knocks on the door, it’s clear that Wolcott is unlocking at least 15 different locks just so he can get the damn thing open.
When he shows Sheldon a notebook with some research and Sheldon says he doesn’t understand it, Wolcott tells him that not only are all his equations written backwards, but all the letters are actually numbers and the numbers are really letters.
