Q: " Do you think Alex and Lacey could be a couple?"
At this point, it's too early to tell. We don't really know much about Alex...yet. Besides the fact that he's Elizabeth's brother. We'll have to see how things go.
Question: " What do you think is behind Charlotte's rude behavior? After all, she's been nothing but a jerk these last couple of days..."
I think what's behind Charlotte's behaviour is that she has a secret. And those awful little things can do some remarkable things to a person. So she takes it out on Lacey. But don't worry, she'll get her payback sooner or later.
