Now I know...

Now I know why everyone hyped the Aquaman episode of Smallville, it rocked. Please don't go shallow on me and talk about Lois Lane in a bikini. Although, no, I'm not going to say it. Is it hot in here now?
Anyway, the storyline was classic. Arthur Curry vs. Clark Kent vs. Lex Luthor and love interests all around. For the first four seasons there have been hints about Lex turning to the dark side. Now in season 5, he embraces the evil pushed on by his distrust in Clark. Think about it from his perspective for a moment, your best friend lies to you repeatedly and everyone THINKS he's the good one. Since Lex is going to be considered evil anyway he should have the fun that goes along with it.
Now the question that will torment me until it's revealed, who will die? It HAS to be
Martha
Jonathan
Lana
If you've already seen season 5 don't spoil it for me.
