Did You Know?


Clark's DNA would be naturally be different to Pete's, as they are of different ethnicity & this would be obvious when the DNA analysis was carried out, thus the lab would want to know why they had the wrong DNA sample. See more »


Chloe and Rachel believe that Clark could be Lucas Luthor. However, in Smallville: Prodigal establishes Lucas as being 18, whereas Clark is 15. So, Lucas Luthor would be 2-3 years older than Clark Kent. See more »


Clark Kent: Chloe, what I said about your mother, I was way out of line.
Chloe Sullivan: It's cool. We all have family secrets, I guess. She left when I was five, so... I came downstairs and there was my dad trying to make waffles. He never even really explained why she left. It was weird.
Clark Kent: I'm sorry.
Chloe Sullivan: It's just hard thinking you weren't good enough for someone to love.
Clark Kent: [taking her hand] Don't ever think that.

Searching the Origins
23 April 2006 | by claudio_carvalhoSee all my reviews

The disturbed Rachel Dunleavy (Blair Brown) arrives in Smallvile claiming that Clark Kent is her biological son with Lionel Luthor, therefore brother of Lex Luthor. She asks for a DNA examination, jeopardizing the Kent. Meanwhile, Lana Lang visits Henry Small (Patrick Cassidy) trying to find whether he is her biological father.

"Lineage" is another great episode of Smallville, showing a search of the origins of Clark Kent and Lana Lang. In a certain moment, the situation seems to be in a check-mate for the Kent family, but in the end the plot resolves. My vote is nine.

Title (Brazil): "Em Busca das Origens" ("Searching the Origins")
