Page "Marshall Flinkman" Paragraph 11

Beginning in the fourth season, Carrie seems to have given up her NSA job to take care of Mitchell.

She is unaware Marshall still works for the CIA, since APO is black ops and he is under orders to keep it secret.

She only appeared in one fourth season episode (" Tuesday "), and prior to the series finale appeared in one episode during the fifth season ("... 1 ...").
