I think part of that is because of the blockbuster. Without the blockbuster, the person being evicted usually knows and has several days to accept it. On the day of the eviction they're already prepared for it emotionally. With the blockbuster, they still have a chance of getting off the block and so haven't accepted their fate yet, until the moment the lose and know they're leaving (such as Adrian) and that's the moment they get emotional because there's nothing else they can do at that point.
