This is the most fanservicey episode ever! Seriously, it took them an alternate universe to make Lois a Pulitzer prizewinning journalist, Clark to sweep her off her feet, her to see his super powers, give Kara the Linda Danvers name, make Kara work closely with Lex for a number of years and trust him implicitly, whilst Lex is President of the USA, and properly eviiil, and also put Clark in journalist and glasses mode?!
Brilliant. I remember back in season 1 we saw a premonition whereby Lex was in a white suit in the White House, and the countryside had been ravaged by what we assumed was a nuclear war, all burned out and blackened anyway. Well that's what transpired in this episode. My guess is they originally planned for this to happen in the seasons properly, but it didn't pan out that way. Hence Lex destroying the world with Braniac in this episode.
Also, Kara is exceedingly heroic in the fortress. Far more so than Clark. Clark is still a bit of a dumbass, but hopefully less emo after this episode.
2 more to go in this season, then bring on season 8. And please god give him the costume at least once somewhere! And flight!
