Snakerjape seems to have only 2 eyes, while Jorbelox had 4. Also Jorbelox had horns where Snakerjape has stylish hair.

Today's comic indicates that Snakerjape is a wandering lurker, not closely tied to Jorbelox or Mechanicsburg. Of course, he could be lying to Egon the waiter. But it appears he wants the Guild Hall back because he wants a place to call home. So far, he's wistful more than malicious.

Even after being told how the key works by two different unrelated people, he's still astonished that it works that way. A skeptic, or an idiot?
