How did Lana doublecross Lionel?

[xrayvision]

Lois said that Lana doublecrossed both Luthors. I understand how she got Lex, but what did she do to Lionel this episode?

[niki]

Because she's a spy for Lionel about all the info on Lex but she wanted to turn over the information to the papers instead of to Lionel!

Oooo ... dun dun dun!
