Before L'manberg, Wilbur was just a man with an RV, guitar, and a dream. Tommy recognized the importance of all of these things, and he wanted to be a part of them all. He begged and begged Wilbur to teach him how to play, and as the walls begin to be constructed around their new nation, WIlbur folds to his requests and teaches him a few simple notes. (Hey everyone, please note that this is a headcanon of mine, and in no way is actually canon. There are some other, smaller headcanons incorporated, which I understand are also not canon. As of right now, it's only one part and I don't plan on making more, but if I get inspired then maybe there will be, who knows? If you want to use this headcanon feel free! All I ask is that if you write another story based off of it, please credit me!! :D )
