This is my first (and poor) attempt at a theory. But I was wondering, how likely is it that Wayn could eventually become a worldhopper? I mean after the events of Mistborn era 2. When I first saw a stranger mentioned on Threnody that was wearing a hat, I started thinking that if the person was a worldhopper, he might be Wayne. After all, we all know his obsession with hats is ridiculous. To be fair, we have no reason to believe that that character in Forests of Hell is worldhopper. But he was mentioned by both Silence and Daggon in passing, and wouldn't it just be epic if Wayne actually was a worldhopper. His skills seem to prepare him for life blending in with the cultures of other planets. He's a master of disguises and an excellent actor, allowing him to move efficiently in any society without drawing attention. He's charismatic, and can quickly make friends, so he can learn about various cultures. Also, he's proficiencient with dueling canes, meaning he can be an effective fighter on planets without firearms and gun powder, even if he doesn't have access to bendalloy or gold reserves. Plus, he seems like the kind of character who loves adventure, and I could see him traversing planets for this reason. Now, as for how he would gain access to the cognitive realm, I have no idea. Perhaps Kelsier, who must be extremely knowledgeable on the subject after being stuck there, could play a role. Anyways, this theory is pure speculation, with little evidence to back it. Still, I want to see what other people think about it. If there are any characters that you think SHOULD become worldhoppers (even if they probably never will, like poor Wayne), please share your ideas.
