Interesting observations. I kinda of agree with your thoughts on Kristina coming to terms with a major blow. I get the feeling they are going to 'hide' the news for as long as possible, for whatever reason. But what we have grown with Kristina is information, especially between family members... flows... quickly.

Yes there is that initial blow. There is than denial. She is carrying some bone crushing news and besides Adam, who we saw told to knock it off with the positive, Kristina is bearing a huge amount of weight. Her lonileness must be killing her... metaphorically. To me cancer news is like news of death to someone. Despite the agonizing crush of information, you don't keep it in. Your surround yourself with family support.

The cat is now out of the bag with Amber. I'll be disappointed if they pull a friends and let this hidden news linger through the season.
