Lex as no right to his secret, period, no one does, and Clark has made it more than clear he's not going to tell him, so really if Lex is his friend, he should respect that and leave it alone.
Also, wanted to say how much I really really enjoyed this ep. Clark without his powers was portrayed so perfectly, and his first mission as a human was very daunting to him, until he adjusted and switched gears, and it was ultimately him that saved the day.
And I really think "super whining" was priceless, there were parts I laughed out loud..and I dont know how they did it, but I really liked Clark and Lana together...any sitatuation that makes Clark smile like that, and be that adorable is more than Ok by me. The sex was handled well, and I loved that he came to her for comfort first..just really well done.
And the smackdown, what can I say? Clark was enraged, and had every right to be, and good for him for goading Lex into hitting him to provide some peace from Lex. As far as Clark knows, this loss of power is forever.
Clark and Chloe together was wonderful, I feel like all the characters are finally aligned as they should be and playing their appropriate part in Clark's life now. I'm more excited than ever about this season now
