I only watch the show -- not the live feeds or BBAD -- so, from what I've seen, Jonathan didn't even seem to want to work with Dina; he apparently just felt a need to protect her. He should have brought her into the alliance at the very beginning. But I can see why he wouldn't want her on the block. She was probably a guaranteed vote for him; if she's also on the block, he loses her vote.
Didn't Anthony say something in the beginning about having to stay at least 12 days? (Presumably to beat his stint at the White House?) I think he didn't want to be the first HG voted on and started making noises about leaving, so they gave him a graceful way out.
I think Kandi said it all at the beginning of the show when she said she has no poker face. When she's annoyed, she's going to look annoyed. (And, I think there are probably a lot of annoying things about being in the BB house.) She doesn't bother me on the RHOA, which is why we might have different opinions here. I think she's one of those people that's motivated by the paycheck and is not really interested in drama for drama's sake. Whereas, Tamar (who I don't know as well since I never watched her family's show, although I saw her on Dancing With the Stars) is the kind of person that likes a bit of drama and perhaps takes longer to process through her emotions. I think Kandi came in not really wanting to get into a big emotional scene with Tamar and Tamar came in needing a big emotional discussion to get past whatever beef she has with Kandi. I think Kandi thought they were done after one conversation and was then surprised when Tamar brought it up again. Tamar seems to have done a better job with socializing with Lolo and the wrestler (I know she has 3 names, but I can't think of a single one right now), although the wrestler revealing her top two deal with Lolo in front of Tamar definitely didn't help.
I've said it before -- Ryan is not a mental giant. Didn't he admit on the first night that he had never watched the show? I'm not sure he even knows that -- as outgoing HOH -- he can't compete in the next HOH competition. Agree with you on Kandi being "completely chill," although she's probably not there to make friends either, so she might have underestimated the social aspects of the game. But, Tamar -- especially her screechy voice -- would drive me crazy if I had to be around her 24/7.
