I don't believe in destiny, but I do believe in foreshadowing. When I rewatched "Splinter" last week in light of "Reckoning" and "Lockdown," I noticed a few things that may be foreshadowing upcoming developments in the season, especially in the Lex/Lana relationship.
Spoilers through Vengeance
"Lana, Lex, Lies"
"If I told you the truth and something happened to you, I'd never forgive myself," Lex says to Lana in Splinter, when she wants to know the truth about the spaceship. Isn't *that* an interesting quotation to be coming out of Lex's mouth, especially given the events in "Reckoning." But it's not just foreshadowing "Reckoning," it's more immediately foreshadowing "Lockdown."
In "Splinter," Lex initially tells Lana that he didn't tell her about the spaceship because he's protecting her. Knowledge about the spaceship, he says, is dangerous--"people have killed for a lot less." Lana suspects he's bullshitting her because he wants her knowledge of the spaceship, and at the time it seemed a reasonable assumption. However, it turns out Lex was right: knowledge of the spaceship *did* put Lana in danger--both she and Lex almost got killed for that knowledge in "Lockdown."
Furthermore, the fact that Lex will trust Lana, rather than lying to protect her, is also spelled out directly in "Splinter", where he tells her that he had to stop protecting her because he couldn't lie to her anymore, and he knew that she was searching for the answers haunting her since her parents died. (Again, in "Splinter" this is delivered as fakery--Lex actually makes this response to try to avoid answering hard questions from Lana--but in "Lockdown" we see he was actually telling the truth, in that classic piece of Lex misdirection).
Lana's attitude towards being protected is split: on the one hand, as in "Lockdown," she is drawn to the equality of her relationship with Lex; each takes turn being the protector of the other. This is the adult Lana, and one of the many reasons why Lana's relationship with Clark is doomed to fail. On the other hand, part of her still wants (and needs) to be protected, and that is the part of her that was drawn to Clark's revelation of his secret in "Reckoning." But ultimately (even if Clark had changed the past in a different way), she needs more equality in her relationships. (I've figured out that's why I liked her first scene with Lex in Reckoning: even though she wasn't necessary very *good* at it, she stepped up to try to protect Clark's secret. She does want to be able to protect the people she loves, not merely be protected by them).
Clark's fears, Clark's fists
"I don't know what you did to trick Lana into believing she was in love with you." This is Clark's accusation to Lex while he is under the influence of silver K in "Splinter." He fears that Lana will betray him, just as Lex has--though her betrayal would be the double betrayal of consorting with Clark's enemy. And this does seem to be coming true: every episode since Splinter has moved a step closer to Lexana. I suspect that what Splinter is predicting is that Clark is never going to be able to accept this relationship as real, and that this will somehow lead to full-out war between Lex and Clark. ("I don't want to hurt you, Clark." "But I want to hurt you.")
"If I'd have killed Lana...." (Clark in "Splinter") Clark does, as it turns out, kill Lana in "Reckoning"--or at least, he contributes to her death. (Interesting that in Splinter he *also* almost kills his dad, and attacks Lex, saying that he wants to hurt him. ) Splinter predicts that he cannot live without Lana--you'd never forgive yourself, Professor Fine tells him. And in fact, the decision he makes in "Reckoning" does show he can't bear to be the one responsible for her death. Does this mean he'll never forgive himself for his contribution to Jonathan's death?
"Those Kents, they pack quite a punch." (Lionel Luthor, "Splinter") Here he's talking to Lex, whom Clark has bruised pretty badly; but this statement also foreshadows Jonathan's death. It would be interesting to trace the significance of all the punches this season. Clark punching Lex in "Mortal" signalled the start of open hostilities between them. Everyone was rightly critical of him immediately after that episode for continuing to punch Lex when he was down. This is not the action of a hero, but it is definitely the instinctive response of a Kent (at least a Kent male raised by Jonathan!). Will Clark ever learn that his father died striking his enemy in anger? I think he *must* learn that, sometime in the future, because I think it will be one of the things preventing him from striking a similar future blow at Lex, which would not destroy him physically, but would do so morally.
Actually, I wonder if Clark would have been capable of saving Lionel's life in "Vengeance" had he known the truth about Jonathan's death. Will he ever find out? Will he be tempted not to save him in the future, especially once Lionel starts his seduction of Martha in earnest?
Predicting the future?
"Lana Lang will never love you, son." This is from the end of "Splinter," in the scene with Lionel and Lex. Is this foreshadowing? Or maybe just a warning from Lionel, as part of the deep game he's playing this season?
latxcvi has been talking about the slow progression of Lexana this season, how they are actually taking time to build an organic relationship between them, and I think that's true, as I have sketched out, a little, above. I agree that Lexana is only going to work for the viewers to the extent that there is mutual desire between them, so I really *hope* that this is just Lionel's usual mindfuck, and *not* foreshadowing.
