I especially liked this part:

Quote
She’s Kryptonite, green with bitterness and jealousy and resentment in a Smallville tent. Green with sickness and guilt and regret in a Daily Planet newsroom. Green with the real Kryptonite that will bar her from forever getting close enough to Clark to finish the job she’s been making her life’s work (that will save him from ever having to worry about her ruining his life again).

I too loved the flash back to the moment she figured things out about Clark being Superman.

I'm a little surprised Lois hasn't been affected more physically by the Krptonite injection. Yet that's not really the focus her, this chapter was all about Lois realizing that she was poisonious for Superman. But we all know that's not true!
