Spencer went down in my estimations after the basketball task.
When Sandy jumped in at the start you could hear PJ saying "Errr, Sandy...." but Spencer cut him off saying "No its OK, leave him". This meant the agreed running order was knackered and Spencer wasn't too bothered at this point.
But then after he realised he was out then it all changed and the toys came out the pram. He needed some one to blame and rather than incur the wrath of Sandy, he picked an easier target, Jonny.
