I have to laugh when all along it was Dexter that was going for the SYMPATHY vote, not Sam.
Having mini nervous breakdowns when he was saved from eviction - his "I only wanted to be liked" "I've never had a friend". The scene with Dan where he sat in the corner and cried because 'he had never had a friend' and he felt rejected by Dan.
And you think SAM was after the sympathy vote. Give me a break!!
Dexter played you all and he succeeded - but NOT with the public!
