Kimberly was a prostitute but when she slept with Victor she was in love with Shane. She was helping him in his investigation of Victor whom Kimberly was a friend of and when Shane was in danger Kimberly slept with Victor to save Shane’s life.
When Kimberly left it was with Phillip Collier (sp) and as far as I remember it’s never been discussed until now that her and Shane had gotten back together since then.
I know I’d read an article that the head writer wasn’t happy with the way Shane and Kimberly ended and when they were planning the memorial for Alice she went to the Executive Producer and asked if Shane and Kimberly could be brought back so they could have the happy ending they deserved. With that I’m guessing they’ve written a little off camera history or are hoping that the viewers won’t remember that they’d separated in 92 or 93.
