No, there is no "sick" connection with them. They have been friends, like brothers, since they were kids. Sampson was raised by one of Alex's aunts, with a lot of help from Nana Mama. Sampson considers the Cross family to be his family as well. The affection between the two of them shows that they are actually secure in their manhood, not that they are trying to hide a homosexual attraction. Get over it, people of the same sex can be affectionate without being sexual.
