What Virginia said. I'll add that her body language says she is really falling in love with Clark and she is afraid that it is too much. She feels threatened by the intensity of the feelings she is having. Clark realizes what she is *not* saying and accepts her fear. He is, after all, a very patient man.
Hope this helps too.

P.S. 2 I blame the mistakes in Lucky Leon by the fact they had a host of writers who changed things as they wanted it.
