Danielle went crying to Kim G. that she wants to find her birth mother. She went to Kim G. because she knew that Kim would "help" (meaning for over the $$$$ for the search.) Because after she asked Kim and Kim said she knew someone who could help, and she would call them, Danielle said "you would do that for me?" So, Danielle knew that she could manipulate Kim for it.
I also don't see what the big deal is about Kim telling anyone that she is helping Danielle look for her birth mom. You didn't see Danielle ask Kim to keep it a secret. And it didn't seem like Christine seemed upset when she asked Danielle at the diner about it, only curious.
The whole thing was baloney.
If Danielle was really concerned about her daughters finding out, from Danielle, that Danielle wanted to 'sniff out' her biological mother, then Danielle should have told them before she went to Kim G. and told her, in front of a cameraman, soundman and producer. Plus, the scene ended with Kim G. picking up her cell phone to call someone to get the ball rolling.
Hence, when Danielle left Kim G's house at least four people, and probably five, knew that she wanted to find her birth-mother.
Here is what I did not understand:
Scene: Kim G goes to Jacqueline's house spitting mad about Danielle, yapping about an email she got from Danielle the prior night, and how everyone was right about Danielle. No mention of what the email was about.
Next Scene: Danielle arranges to meet Kim G in a restaurant, so Danielle can chew out Kim G for talking about her baby-momma search. However, the whole argument is rather incoherent. It looked like Kim G was already mad when Danielle showed up, but she never mentioned the email. Danielle acted like she had not previously communicated with Kim G, via email or any other way. Any clarification would be appreciated.
I did like how Kim G. quickly chased Danielle out of the restaurant.
By the by: I agree about the creep-factor of Danielle taking her eldest daughter to the doctor and trying to get said daughter to talk about sex life, boyfriends, etc on camera.
