Other mistake: Abel was 18 months old when Thomas was born. All through the series, Thomas hardly ages. In season 7 Abel is 5 and in kindergarten yet Thomas looks younger than 3. He's not even walking or talking yet! Thomas should be at least 3 years old according to the time span of the series.
Continuity mistake: When Patterson first visits Toric at the hotel he is on the second floor. When Roosevelt visits to investigate the room is ground level.
Chosen answer: The First 9 wore these, as can be seen on old pictures. They later switched to leather, but Piney just never did.
