Little is known about Don’s appearance at this point, but the episode is slated to be shot in April, likely placing it anywhere from episode five (“Uninvited”) to episode seven (“Counterstrike”) on the season’s production schedule.
Davis departed the show after Season Seven. General Hammond’s last return appearance was “The Fourth Horseman, Part 2.” It is likely that his appearance this year will be as low-key as it was in that two-parter, but this remains to be seen. Stay with GateWorld for the latest.
