I hate to get my hopes up, but after watching the episode IDENTITY, it really seems they're doing it. They're actually taking the Clark Kent story directly towards and into the Superman story. The series began well, right on track with how it should've gone. Unfortunately they milked the young CK story too long. I don't want to dwell on that this time, though. They've actually and finally moved into the adult CK's life. He's becoming a super hero, and they aren't sending him on endless side-stories. This season could actually see the emergence of Superman.
However, I don't believe we'll see him in tights in the next episode, or the soon-to-come episodes either. They need to pace the transformation now that it's actually began, and it appears that's exactly what they're doing. A young man with extraordinary abilities and virtues doesn't step into the public eye--especially wearing a bright red cape!--overnight. They're describing it as it happens, and better yet, are giving reasons good enough for us to believe and accept. I hope they keep it up.
As for Chloe, they've actually piqued my interest. She definitely drifted a bit more towards the Dark Side this episode, and you could see it bothered her by the expression on her face at the end, unless she was just trying to make herself hard. I'm no expert on the comics, but the classic reporting team was Clark, Lois, and Jimmy. I think if they mean to fully synchronize the storylines (as much as is possible with the current history), Chloe cannot remain indefinitely. At the end of the last season I was certain that Chloe would be absolutely critical in the story for *some time*. I still believe that. Nevertheless, there will come a time when she too will need to disappear.
My firm belief, however, is that her removal will need to be meaningful. She can't simply run off to live with some uncle of hers in another state never to be seen again, and she can't just die from some random mugging that Clark was too late to stop. When she goes, she will have been the last person still in CK's life (unless you include his mother) to fully know and support his secret. With her gone, Clark will have to have fully grown up. He will be essentially alone, with no human to guide him, and then he'll have to be strong enough to make his own decisions instead of being led to them by his friends and family. It will have to be his choice to be Superman.
I believe the best removal for her will this time also be the easiest--death. Not trapped in some Phantom Zone, not mysteriously disappeared; but gone for good. In fact, I believe that this death will be a final motivating factor in Clark's transformation. Somehow, as a result of her demise, he will dedicate himself to truth and justice by means of his superhuman persona. It is my belief that at the rate this season is going, this death could acceptably come in the end of the season. Whether CK dons the cape in the last episode of this season or the first part of the next, I can't be sure. But it is coming.
My speculation is that Doomsday himself will kill Chloe.
I'll regret her loss, and cheer the birth of Superman.
