Did he not also say to Ben that he has his back , and hinted that for him(Mario) to have his back means a lot.

Nah! T'wasn't a fix.

Think people need to stop getting paranoid, Mario is probably one of the least interesting in the house so I'm certain BB wouldn't have fixed it for him to go in.

Nah. Mario can't stop the public voting Ben out, if they decide to. He couldn't even stop Shabby putting him up for eviction.

They had to pick someone his size to get through the vents they couldn't have chosen a large or disabled person.

Granted some names may have been removed from the tombola, like the girl on crutches, or the girl with no arms, but it wasn't planned for Mario to be solely picked. Although they could have changed the tasks to suit the less nimble people.

They could have changed the task to suit whoever went in.

Very good point!

I really don't think it was a fix, what would be the point? He is one of my favourites but I'll admit he's not like 'Mr. most exciting housemate ever' so it would just be completely pointless.

Plus wouldn't it have come out by now if that were the case? I can't imagine it staying a secret for long.

I think they shot themselves in the foot by not showing us the names in the tombola. When someone suggested to George on BBLB that it was a fix he said "We had an official there to keep an eye on us" Then he rolled his  eyes and laughed. Let's face it they have form for cheating look back at the Golden ticket. Susie told all her friends she would be in the house and her name was drawn out of a hat.

I still don't see how people think the Golden Ticket thing was a fix. We all saw different numbers on the ball and we all saw Aisleyne pick the ball, how could it be a fix? I just think it was an unfortunate coincidence that Suzie got picked.
