After a boy with superhuman speed saves Jonathan---and steals his wallet---Clark tracks him down and discovers he's a homeless kid who uses his powers to commit petty crimes. Also, Lex acquires an ancient manuscript with Kryptonian symbols, and Clark learns that it contains a mysterious map; Jason discovers Lana's tattoo.

Clark accidentally injures another player when foreign-exchange student Mikail Mxyzptlk uses a form of telepathy to make him trip during a big game. As a result, Jonathan wants Clark to quit the team before he hurts anyone else, and Jason suspects Clark is using steroids.
