I hate that everybody in the BAU has an office except for Reid, he just have a simply desk, he is a Doctor.
Carmy: J.J no longer has an office ‘cause she is the lowest ranking profiler now, nor does Blake.
JJ, Reid, and Blake sit out in the bullpen. I thought Morgan would go back after Hotch was reinstated as Unit Chief but it looks like he still takes on paperwork and some things because Hotch is a single dad and needs to get home. So he stayed in his office. Reid isnt all by himself.
