Ouch!

However, I have to wonder why you started this story at the Kerth ceremony, so I'm sill holding out hope.
I'm with the rest on the sheer idiocy and irresponsibility of Clark freezing Lois in the first place. If his parents had died, that would have been terrible but it would have been Mazek's fault. The fact that Lois got turned into the Bitch From Hell is, in fact, very much Clark's fault. He is reaping what he sowed.
I can only imagine that the grounds for suing the Planet would be that Lois was injured while on duty. It would make a self-defeating lawsuit, though. "I'm suing you all for turning me into a bitch." That would do wonders for her reputation.
I seems that not only is Lois a sociopath, she doesn't even have real self-respect any more. If she did, she wouldn't care about winning an award that she knows she didn't earn.
If she does come back to her senses, I hope you will give Clark a little time before he trusts her again. Even if he knows in his head that she isn't really responsible because of the brain damage and that it was his fault to begin with, he's still got a lot of hurt feelings to get over. He won't be able to turn on a dime, even if she somehow does.
