Lois' barfing might have been a reaction to the chloroform. Some people even today have that reaction to anesthesia upon awakening, and we have much better drugs nowadays.
In a previous post, Ann wondered (I'm paraphrasing here) how Lois could access her "Mad Dog Lane" side if Deter had so completely changed her personality. The answer is that he hasn't done any such thing. All Deter did was facilitate a transfer of Lois' emotions about Clark - whom she could not consciously remember - to himself. It's a common effect in therapy anyway, and with a traumatic amnesiac patient the effect would be more pronounced. Deter just didn't take the steps he should have to prevent the transference. (The slimy worm.)
I like the way Clark is treating Lois so far. He's giving her all the space she wants and not forcing her to do anything, even eat or drink. I'm not surprised he couldn't look away when he saw Lois naked, but he's got to know that such images will make his self-appointed job harder.
A thought: If Lois remembers that Clark and Superman are the same person before she remembers that she loves Clark, what will she do? Will she start looking for kryptonite or throw herself into his arms and "convince" him to fly her back to the mainland? Or might she do nothing and wear Clark down so that he gives up and takes her back in a boat or a chopper?
This is an interesting premise. How do you gain the trust of someone you've taken against the person's will without creating an unhealthy codependent relationship? I'm looking for the next chapter now.
