Back on track... just watched the first episode and didn't really get it. Why did Chloe trade herself for Oliver Queen, and why would whoever holding him want Chloe instead? Why did Lois, after finally finding out who Clark was, suddenly bug out at the end of the episode? Were those just two incredibly lame and nonsensical plot devices to explain the fact that Mack and Durance weren't going to be in a lot of episodes?
