Allegre is right - we never saw the scene where B&K told the family. It would have been a very good and powerful scene though...its a pity they didn't do it. And yes -Blake was losing the love of his life...

but was also worried about whether he was going to be charged with murder

And poor Krystle - she was so worried about how this was affecting Blake and how her illness would affect Blake and Krystina - so much heartache!!!!

Just one criticism of Blake though...he should have eased Krystle's fears about killing someone a lot earlier when he knew whose body it was. She was thinking she had gone crazy but he knew she couldn't have killed him....
All in all....very dramatic storyline with both characters worried about so much - and about each other. But of course the most important thing was that Blake knew he could lose Krystle forever.....
