Oh yeah, and the reason Dexter was nervous, was not because he was in the wrong but because he's intelligent enough to know that it would look bad for him to be perceived as picking on someone with a disability, even though he wasn't.
Kudos for Dexter for daring to point out the negatives of Sam and not treating him any different. Charlie or the Twins, for example, would never dare say a word against Sam, especially when they saw he was second favourite.
