After Martha accidentally hits a young boy with her car, the Kents take him in until they can locate his parents. They are unaware that the boy can read minds and has discovered the hidden thoughts of Lex, Lana, Jonathan and Martha, putting Clark's secret in jeopardy. Meanwhile, Lex must decide if he wants to accept a job offer from his father, Lionel (recurring guest star JOHN GLOVER), which would entail moving back to Metropolis.
Ryan (from "Stray") returns and Clark has to save him from Dr. Garner of the Summerholt Research Facility. Meanwhile, Aunt Nell leaves Smallville, and Lex wants to expand the plant but runs afoul of the mayor.
