Formerly titled as Only the Lonely, The Forsaken is a literal and figurative deconstruction of Odo.
On the surface, he is the powerful alien shapeshifter; Deep Space Nine’s security chief, incorruptible, just, and a talented investigator. He frowns at imagination and romance. His natural form is liquid and every 16 hours he rests, somewhat undignified, contained inside a bucket in his office.
Buckets notwithstanding, he’s clearly a being you don’t want to mess with. There is another side to that: Odo really is pretending 16 hours a day at being a solid.
