Why is Shawn so hesitant when trying to make a decision. I am really tired of he and Isabella. She is too forceful and I really don't understand her purpose. She has said that she is there to destroy all of the 4400's.He has told her that he does not love her why is she so intent on marrying Shawn who is a 4400. I have more questions now than I had before. Tonight's show didn't answer a lot for me.

Shawn is hesitant because he is afraid of the consequences. Like anyone with a gun to their head, he is afraid of saying or doing something that will get him killed. Isabelle is not only emotionally immature and a little unstable, she is also capable of full-on spree killing and she has threatened Shawn's family. If Shawn knew that he'd be throwing his life away to stand up to Isabelle he might do it. The real choice he has is that standing up to her might cost the lives of everyone he loves and who knows how many innocents as well. I don't agree that he's weak-it's hard to tell how strong someone might be when they're under the kind of duress Shawn is experiencing.
