We reported awhile back that AJ Cook was returning to Criminal Minds next season and now we have learned that Paget Brewster will be back as well. Since her character faked her death last year, it will be interesting to see how they bring her back.
Less fortunate, however, is Rachel Nichols who will not be returning in the fall. Nichols sort of took the place of Cook and fans immediately did not like the plan of Nichols on the show (who also bore more than a passing resemblance to Cook).
Finally, Thomas Gibson is still in negotiations to return to the CBS drama, although that still could turn south (see Lisa Edelstein).
