LaT and I are definitely speculating that it's the key to the chamber, but who knows? I think it's what Helen gave Lionel last year in that envelope that Lex saw them exchanging pre-wedding. It would be interesting to see Clark's reaction to that room. *g* The Rift is here, either way, but that would certainly take him aback to realize that Lex doesn't really need the memory of seeing him use his powers to know his secret. He's already got it pretty much figured out. And I think that Clark learning exactly how compartmentalized Lex can be--how he can be gathering a collection like that and you'd never have so much as a hint that it exists? Is something that the future Superman needs to see. Clark is still a *long* way from stepping his mental game up enough to play on the same field with Lex. This could be just the kick in the pants he needs.

Maybe it would be too obvious..that it's the key. I dunno. I just think that the way the room just was never mentioned again, it sorta has to come back.

And Clark's reaction. As much as I don't want it, it has to happen.

Actually, I think Clark is in denial more than anything else. In Talisman, Lex told him downright, that he knows who Clark is, what Clark is, it seemed to me he was dressing him in the end. As if he knows his role and Clarks role and understands it far better.

Clark should know by know that there are no secrets left.

So yeah...he needs to see things more clearly.
