What is your goal?

I want to show how Clark and Lana never would have stayed together, even if the proposal had stuck in "Reckoning" and she knew his secret.

What are you going to do to accomplish it, given the constraints on your powers?

I would have the power of damaging electronical devices so Lana would never receive the phone call from Lex.

What do you think the effect of your change will be?

I think they would have been engaged, but during the time before the wedding, Clark's constant need to save other people would annoy her because she thinks she should become first in Clark's life. And I think she wouldn't have been too thrileld with all of the talking between Clark and Chloe since she would feel that he could talk to her now that she knew the secret. Plus, it would have allowed Clark to move away from Lana with a clearer and sound mind by not having the "what if?" factor hanging over their relationship.

What might be the unintended consequences?

That Chloe might think that Clark doesn't need her anymore, which I think would be untrue.
