I think he has alot of potential for both good and bad. Sounds like he'll be a good conversationalist but he'll also have some quite stubborn views.

I don't like how Danny has already labelled him as fake. Seems a bit harsh questioning a 19 year old's character while a large group of people are just starting to get to know eachother. I'd understand if he was attention-seeking or stirring things up but surely at this point everyone is being cagey just trying to find their place within the group.
Personally I think Danny has some major insecurities and is currently projecting them onto others to make himself feel more assured. So far he's done it with Aaron, Sarah and Joel, who'll be next I wonder?
