No I am not speculating really.

I have seen Mario asking for tasks in that DR and nothing. Yet Sammy boy goes in and asks what viola! A task is dutifully handed out.

I guess it matters who is doing the asking.

Lol, well you are speculating about it because you don't know for sure that BB did set the task up for Sam to gain affection from the HMs or public, just as much as I don't know fur sure that BB didn't.

I guess it also matters whether the producers decide "We haven't used the Tree for a while", or "Better give Dave the letter or the sh!t will hit the fan and we'll have Ofcom on our backs", or a number of other reasons

Its almost certain that they are both out. John James' fans will be voting out Sam, and vice versa. Not good - they both deserve a place in the final!
