This will in no way be a comprehensive spoiler, because I have a memory like a sieve. Consider this a snack to tide you over.
[spoiler]The man Lex “killed” turns out to be a pile of dirt, and Lex is holding a stick, not a machete. There is no blood on him. In short, it was all a dream. And Lex may be going crazy. At least, he suspects he is.
Chloe spills to a desperate Lana where Clark is, which leads to Lana confronting Clark, which leads to Clark on the phone with Jonathan. Spurred by the convo, Jonathan takes the octogonal key and uses it, which leads him to have a disturbing conversation with Jor-El , where Jor-El is more concerned with Kal-El’s “destiny” than anything puny Jonathan has to say.
Clark takes the job from Mr. Edge and breaks into LutherCorp’s HQ, where he is rudely interrupted by Jonathan, who, showing superspeed and strength, grabs Clark and jumps through the plate-glass window. They plummet towards the ground.
To Be Continued. [/spoiler]
