Not a fan of Harry's but, I have thought about what Harry said to Danny re: Nick etc... I have feeling she may have been genuine there.

And .... Danny came over well.

I disagree. he seems to have a problem with Nick.
Danny and Jack were bitching about Nick in their tower the other day. So when he asked Harry how she felt about Nick not being there, it just sounded inappropriate to the immediate situation. It's not what you'd say if you were genuinely consoling somebody.
He seemed to be completely oblivious to why Harry might be feeling the way she was feeling, and anything she said was meaningless as he kept trying to pin whatever it was onto Nick.

For the last week at least, it has become apparent to me that Danny doesn't like Nick, and I wouldn't be surprised if Danny nominates Nick the next chance he gets.

Probably jealous of Nick for being the house stud , while his little dalliance with Sarah was nipped in the bud earlier than he hoped.
You see it doesn't look good for Danny if some little runt in the house is getting all the women while Danny the BB house beefcake has none. It must be embarrassing for him Nick being there and putting him to shame. Danny is fit, Nick is not, so how can this be possible in Danny's reality? Imagine how Danny would think it would look to the viewers.

I hardly ever see Danny and Nick having a good chat. I just think that Danny can't stand him.
I bet it makes him feel sick to the stomach that even Nikki is adoring Nick too.
