(S02E01) After the harrowing conclusion from last season, Mary Shannon was back and after 30 hours of sleep, she actually seemed ready to return to work. However, as Marshall soon found out, looks can be deceiving. Mary and Jinx and Brandi were still together and coping, but the effects of one of them nearly being raped, killing a man, concealing drugs, having their home turned inside out and suffering the indignity of the FBI invading every corner of your life took a toll. They thought they had come out the other side unscathed, but as the episode unfolded, damage was evident.

For Mary, getting back on a case, even as Marshall's sidekick, was a welcomed relief from administrative leave. Her denial of post-traumatic stress disorder was typical for her. In fact, she was suffering, but it manifested itself as a happy, chipper and congenial Mary. Stan, Marshall and Bobby D. were baffled by this alternate universe Agent Shannon, but for viewers wise to the ways of TV, it was clear that something was amiss.
