The 24-year-old actor was joined on set by a very happy Candice Patton, who plays Iris on the show.
“Sometimes I just love wearing this suit. 2 more days of shooting before we go on break. Get hyped for our return on Jan. 20,” Grant reminded fans on Instagram during some downtime.
After wrapping, Candice and Grant were seen saying hi to fans and goodbye to their crew.
