I don't think Joe as been as funny or as entertaining as DVD. and for Joe to believe what Nicola said about a plan DVD thought up...
DVD also acknowledged that Joe stood up for him and when Timmy left and it was decided they would all start anew DVD stopped winding Nicola up but tried to keep a sense of fun in the camp but she used his suggestion to get Joe back on her side because I believe Joe's temper gave her cause for concern.
DVD tried to ingratiate himself into the group and was/is unaware about the lie the two-faced Nicola has planted in Joe's head.
As you said DVD has two lovely daughters, he must be doing something right.
Nicola sure is direct but like a lot of direct people she doesn't like it when people are direct back at her.
Nicola getting voted out of the jungle before DVD was good enough for me gg, and from the interviews i have seen her do since she left it looks like she has not learned her lesson because she is now slagging Joe off and has said she is going to have a word with Ester over comments she made about her.
So all in all it would appear more people saw her for what she is and got rid of her and they have kept DVD in because he is entertaining them, and me, that is the reason I think he should win, not because I like him.
