I was wondering how Kim was going to get her hands on Bobby.  More importantly, I was curious to see what kind of person Kim actually was.  The cool thing is that I'm still not sure, especially with the way the chapter ended.  It's hard to tell whether she just likes to tease Bobby and is angry that he won't trust her, or if she is a legitimately cruel person.  Such ambiguity has me very anxious to read the next chapter.

I liked how Sarah felt she had to make sure everything was cool between her and Bobby in the car.  While Bobby wasn't too bothered by her eariy behavior, it didn't sit quite right with me.  It's good to know that, after coming to her senses, her previous actions really seemed wrong to her.  Of course, if she would have adhered to her promise of not playing with Bobby, not even a little bit, she wouldn't have lost him.  I'm sure she's freaking out right about now.

I can't stress enough how good you are at giving us readers Bobby's perspective.  Those little niches, such as his parts unknown comment and his babbling about the size of the mall building give his thoughts a greater sense of realism.  Keeping Jen as the dominant thought on his mind makes a lot of sense, too.  His descriptions continue to be great as well.

Maybe Bobby can take comfort in knowing that if he never grows back, that means Jen can stay big forever?

Oh, and one minor thing.  The word is terrified, not terrorfied.  Also, no rocket ship mentioning in this chapter?  What's up with that?
