Kara (Laura Vandervoort) and Jimmy (Aaron Ashmore) attend a "One Republic" concert and one of the roadies turns out to be former Smallville resident Pete Ross (guest star Sam Jones III). Pete unwittingly chews some kryptonite-laced gum and develops super powers. Clark (Tom Welling) and Chloe (Allison Mack) are thrilled to meet up with their old friend but warn him against using his powers in public.

However, Lex (Michel Rosenbaum) discovers Pete's powers and blackmails him into helping break into a Lionel's (John Glover) safe by threatening to reveal Chloe is a meteor freak.
