People in the Zone told her about kandor? Wraiths? other people who were evil right before she killed them? Were there nice people living in the zone who had reformed or just grown tired of being evil? Excuse me for saying but just how naive is this little blonde girl? They were fucking with her. That's what idiots are for, you make them believe bullshit and then you have a bit of a laugh.
"If you type "internet" into google, the internet will explode."
Really, if she had friends and allies in the Zone, then why was she alone? had they been killed 5 minutes earlier, or where they only pretending to be friendly to get out of the Zone, or di they just tire of her blonde vapid insipidity and ditch her while she was sleeping?
This is what I would have done.

Kara: "Where's Lex?"
Clark: "Gone."
Kara: "what do you mean gone?"
Clark: "When the Fortress collapsed... What does it matter to you?"
Kara: "We were living in the same house Clark."
Clark: "because he was keeping you a prisoner because he wanted to know my secret."
Kara: "No, because we were sharing a bed."
Clark: "What?"
Kara: "When I'd lost my memories and thought i was human, I'd fallen in love him, and before that... Do you have any idea how attractive that man is?"
Clark: "What? But... he was our enemy!"
Kara: "If things hadn't gone so pear shaped I probably would have married him."
Clark: "No, no... That's not true, that's impossible."
Kara: "I should go look for him. I'll touch base from time to time."

You all know that there's like an 80 percent chance that Lex Was Digitised and he's living "on Krypton" inside the Clark's Crystal?
