I think they have both realized how unpopular she is on the outside and may try to keep her in, anticipating that all 3 of them will be there at the end for the final public vote.

Possibly, but if all the censored stuff was about how Jade is being perceived, then they might want to put some distance between her as they may feel that they will look unpopular with the public.

Why are all the conspiracy theories centered around Alex and Adele?

It could be just as easy to say that PJ, Kate and Jonny would keep her in for the same reason.

true.it would be to the advantage to kate etc as it would mean more chance of them winning/getting a higher place

That's a good point actually, I never thought of it like that. They both know that Jade would have no chance against the two of them and would automatically get 3rd place.

I think Jade will be up for eviction next week. now sophie is out of the way tim could actually nominate her.

I think its much more simpler than that .. that they merely think "its better the devil you know" .. and in Jades case they at least know her ways and how to "handle" her... If you can keep Jade "on-side" its an advantage .. and next weeks nominations/eviction is going to set the tone of the house for the rest of the series..
