Freedom Reborn

Souders and Peterson revealed that the theme for season ten will be "facing the ghosts of your past and how [the effect of seeing the past] helps you move on in the future"; as such, the return of previous cast members will play into this. Souders and Peterson have also chosen not to erase Lois's memory of Clark's secret, something she discovered in the season nine finale. Instead, Lois will help Clark do what he needs to do to get away and fulfill his destiny without telling him that she knows. The producers explained that there would be "some twists and turns" before Lois tells Clark that she knows. In June, Michael Ausiello confirmed that Tess Mercer will be "reincarnated next season", after having died in the season nine finale. Initially helping Clark and Oliver at Watchtower, a secret from her past will define whether Tess ultimately ends on the side of good or bad. Chloe's ending will also be told "in a way that's fitting for Chloe." She will "sacrifice" herself for Oliver, who has been informed that she was killed. As a result, Oliver will spend much of the season looking for Chloe, trying to find who is behind her murder.

Similar to season eight and nine, there will also be a new main villain. The producers revealed that Darkseid will fulfill this role for the final season, but will be a different incarnation than his comic book counterpart. They explained that Darkseid's presence will be felt throughout the whole season, but that he will not actually appear until near the end; unlike in previous seasons where the main villain was present from the start. Instead, Darkseid's minions—Granny Goodness, Desaad, Glorious Godfrey, and others to be named—will appear throughout the season as the physical presence for Clark to battle. The executive producers also wanted to take a look at the history of Smallville's Clark Kent in the 200th episode of the series. According to Peterson, "[The episode will] explore a little bit of the past, the present and the future. We kind of do a little look back to where we've been and we also take a look at where Clark is going."

Is that the costume from Superman Returns?

They were actually offered both movie costumes, but thought the Returns costume worked better for them.

I wish the powers that be in the Superman verse would let that movie die!

Clark Kent and Lois Lane!

The man Isis was trying to resurrect was Teth-Adam

In last week's episode, Lois made it sound like Clark telling her his secret was a lot grander than it was.  I mean her response was classic (maybe) but an office at The Daily Planet is hardly a big deal of a place.  I guess I was just hoping for the rooftop.  LOL!

I don't think Tess will make it through the season finale.  I mean... it's kinda obvious that she isn't going to be trustworthy in the long run.  Does anyone think she will either be forced to betray Clark by Luthor or that she will sacrifice herself in some way so that she doesn't have to choose between them? 

the teth adam revelation made me smile (and kinda disappointed the resurection didn't work temporarily so that we could see black adam), and the final, even if it was anti-climatic (i had a bet on the rooftop too ^^) it actually made the show go forward.
Green-Arrow/Tess are clearly a better duo of actors than Clark/Lois, and i enjoy their scene more so i hope Tess won't die/leave mid-season.
I think she will either betray Clark for her Luthor (because if i understood he's aging faster than a normal kid?) or even better, when her luthor is adult he still will become evil and when she'll try to oppose he'll kill her, making him finaly snap and blaming Clark in the process (or "how to create an arch-nemesis 101")

The Scarecrow?

Raven. There's already one Titan on the show, why not another?

The revelation saved the entire ep. IMO.

Green Arrow saving the day was pretty cool. Working in the Isis/ Osiris/ Teth Adam connection was a nice nod to the fans as well.

Teri Hatcher's cameo was rather disappointing, mostly due to the fact that Erica Durance can't act, and her emotion scene was painful to watch. But Teri's monologue was very bland and generic too.
But on the other hand, Granny Goodness! We got a nice look at the Fury (using kryptonite weapons instead of being aliens works for me, they can still be a challenge for Clark) and Tess is now Lex's half sister...disturbing, but let's see where they go with that (it goes nicely with the sex tention between her and alexander, adding incest to the likely oedipe complex the kid will develop when his accelerate growth is finished).
And finally we see that the season finale will probably be th wedding. A little obvious, but after all it was a memorable plot of  "Lois and Clark" and nobody complained then (except if they redo the clone wedding)
So yeah, mixed feeling. Definitely not as good/fun as the isis episode, but set things in motion for the following ones (granny + desaad + goddfrey...)

The Lex clone Alexander will become Superboy! (http://www.comicbookresources.com/?page=article&id=30823)
