According to spoilers, "Nemesis" is supposed to be about Lex & Clark trapped together somewhere, talking about where their friendship went sour. Whether this will be only a bit of the ep, or the whole ep, I have no idea, but...I have hopes.

I even kinda want Clark to make an overture of friendship, and for Lex to shoot him down. Because Lex has a right to...and it might get Clark guilting and mourning what he's lost with Lex, once it's too late to get it back...)

(...well, really I want them to kiss and make up and divorce Lana and marry each other. But since that's never gonna happen in show canon, I'll take Clark guilting...)
