Tom's Anonymous Thief

Tom's Anonymous Thief is an unseen antagonist mentioned in Eli's Wonderful Life. Who he is is unknown, but Shad Markly falsely claimed it was Eli J. Brown who stole Tom Christian's go-karts and Tom believed Shad and wouldn't listen to Eli when he said he didn't steal the cards. Because Shad had made up the lie that Eli had stolen the cards, Eli believed that Shad was the real thief and that he set Eli up. However, the alternate timeline showed that Tom's Anonymous Thief was somebody else as Tom mentioned that his go-karts were still stolen despite Shad's absence from this reality.

Trivia

 * It's not known if Tom's Anonymous Thief was a minion of Shad's or if he intended to get Eli blamed for his crime, but whether Eli's framing was in this thief's intentions or not, he is still guilty in his own right.
