Do the Insiders genuinely like each other?
 

Like, I know Adam, Lauren and Luke A were genuine friends but I get the impression that the friendships that the Insiders have aren't necessarily genuine. For example, Scott and Luke S are both insiders yet Scott has nominated him twice and does not like him. I also got the impression that Luke S wasn't too keen on Arron.

I think Ashleigh does but not sure about the others.

Nah, they're just together for voting numbers only.
Conor despised Becky and Scott until he realized the Insiders were on the ropes and needed extra numbers so he went and 'apologized' (aka 'intimidated') them into the Insiders ranks.
Also, Conor wouldn't give Caroline the time of day, nor would Ash or Luke S, in the outside World.

They might not all be amazing friends with each other individually but they're a bigger and more loosely connected group than Adam, Lauren and Luke A who were a pretty tight knit trio. Within the Insiders you do have genuine friendships though; Arron & Conor, Conor & Ashleigh etc.

I think most of them treat Ashleigh like a puppy dog - they humor her, but wouldn't want her around outside. Luke S really doesn't like Conor much. Caroline considers them all beneath her, and Conor is a novelty to her, not someone she'll talk to about anything important. Scott, who's at best a fringe Insider, seems to deal with most of them as people he'll tolerate since there's nobody there he actually likes.

Yeah, the Luke S/Conor friendship doesn't seem very legit. As much as I dislike Conor, its quite clear he bounced off Arron more.

Only possible friends in that bunch are Caroline and Scott, the rest just get along 'cos of the voting, in the real world they wouldn't be friends at all.
