We have yet to see the actual disagreement, but this video shows they have made up:

The arrogance of the guy, wanting her to come towards him for a hug.

He only said it because there was a lot of cigs around her as he called it the "suicide area" or something. I'm a non smoker and I wouldn't even hug a person whilst their smoking. The smell makes me sick.

She had finished smoking and he was already in the smoking area, i just saw it as pathetic on his part.

Are you being serious? He was playing around with her, as was she with him. "You come here". "No, you come here" etc. They were messing about...and that was obvious.

She ain't taking no crap from anyone , I actually like her

I think he was trying to prove a point, he feels like he has sussed her out. Cant remember who he was talking to but he mentioned that he thought Sarah, was someone who is used to always getting her own way in his opinion. So i think that was a little psychological/social point he was trying to establish with her,

I sort of got that from it too. I do think people have miss-judged Cristian too quickly and he might be a more interesting character than people actually think. I posted in another thread earlier about how in last nights episode alone, Danny tried three times to get him to agree with him that Aaron is a bit "sketchy". The first two times Cristian said he hadn't spoken to Aaron enough yet to make up his mind on him. Danny didn't like this. Danny then said it again a third time and Cristian said that he had spoken to him now and likes him. Danny looked a bit put out. I could be wrong, but I think Cristian there could be more to Cristian than we think and he might be a pretty good judge of character.

Same here. You could sort of see the look on her face that she was surprised at the arrogance of it.

I am in no doubt that he was trying to prove a point. I believe that the task that pitted male against female was an attempt to draw out the alpha male and alpha female types (or those who believe they are) from the group.
The task, from what we know, had cringe-worthy past information from both Cristian (he believes that he should be in CBB) and Sarah (Money turns her on). From the little snippets we have to go on, some of the men took issue with this revelation (audition nonsense really ) from Sarah and this possibly and conveniently deflected from Cristian's equally, if not more, arrogant audition spin.

His attempt at 'sussing her out' distracts from his own misgivings. That's my take on it so far; Perhaps tonight's highlight show will change that.
I could see from the first night that he is in there to play the game -which I agree makes him interesting, but depending on how he plays it. The snippet in this vid does not hold out any hope, for me, that he will play it well. He exudes too much arrogance here, but as of yet ,we don't know what exactly she has done wrong so we may be able to judge better tonight, i hope.
