A mentally ill man living in San Francisco's Sanctuary District A in 2024, who finds Jadzia Dax's combadge and is coaxed into returning it in Past Tense, Part II.
Grady is a resident of Sanctuary District A in the two-part third-season story Past Tense, appearing in the second part. He is one of the so-called dims, people with untreated mental illness who have been shut away in the district with the homeless and the jobless.
When Jadzia Dax was first picked up in 2024 her combadge was taken from her, and during the riots she slips into the district through the sewers to recover it before it can alter history. The trail leads to Grady, who has been wearing the device and believes it makes him invisible to those who are watching him.
Dax wins his trust by going along with his fears rather than arguing, and he gives the badge back. The brief scene puts a face to the people the districts were built to hide.
