Wow...Arianna sure is bold for just flat out telling her husband that she's still in love with another man.
It's almost enough for me to feel sorry for Lex.
There's no way Lana could have expected anyone from Metropolis to go to the wedding. She burned Clark; she can't possibly think that would draw friends to her side. Nice way of using the wedding as a way of bringing all of the supporting characters back in to the story.
