Dumb question for "Smallville" fans

Do the other characters realize he’s Superboy? Or please explain it to me if I’m all wrong!

Pete (the black dude) does. His parents know, Lional Luthor has an idea and Lex has suspicions.

Smallville’s first season was decent entertaining.
The second season, however, was awful, just awful. I hate all the characters equally now, Hate them hate them hate them!!! They’re either morons, caricatures, self righteous pricks, drama queens or a combination of the four. God, I hate them so much!
