Jo believes Sam has the ''entertainment value'' to be saved in the 'Big Brother' public vote tomorrow (13.08.10), but John James isn't convinced.
Jo thinks Sam is safe from eviction.
The 21-year-old graffiti artist has infuriated his housemates with his prank-playing and outspoken ways, but the other 'Big Brother' contestants think he provides enough "entertainment value" to be saved when he faces the public vote tomorrow (13.08.10).
Jo told John James and JJ: "Bottom line is it is an entertainment show. When I'm sat at home on my sofa, I want to be entertained.
"The thing about it is that a lot of what he does is actually funny and there's only a few bits that are a bit close to the mark, but he is trying to entertain himself and others."
However, though he understands why Sam's antics could be seen as entertaining, John James doesn't think the vegetarian's behaviour will endear him to everyone.
He said: "I dunno, 'cos Sammy throws a massive spanner in the works. he's one of those people who you either love him or you hate him.
"That could work against you in a show like this 'cos the people that do hate him will pick up the phone. If they could vote to save he would stay."
Jo and John James also admit they don't think Dave is completely trustworthy and think that could jeopardise his place in the house.
The Australian said: I do think he's trustworthy, I'm not sure with everyone, though. I think I can trust him but if I was other people...
Jo admitted she has a strained relationship with the minister, saying: "We've got the Common ground of God and religion but that just shows you... that doesn't mean anything."
Sam and Dave face the public vote along with JJ and Jo.
