A mysterious woman shows up claiming to be Clark's mother, prompting the Kents to tell Clark what happened after they discovered him in the cornfield that fateful day. Clark discovers why his father hates the Luthors how his adoption was fixed, and who really rescued Lex from the edge of death. This was a very well crafted episode, but I have one question: why don't Jonathan and Martha get any say when the sheriff arrives to pick up Clark for the blood test? I'm really confused by that?
