It's a typical Sunday in Atlantis and everyone is going about their daily lives. A handsome scientist, Dr. Branton, who is smitten with Dr. Weir is trying to convince her to go to lunch with him. Although Dr. Weir has a personal rule against dating the people under her command, he persuades her to just "have lunch" with him.

During lunch, Dr. Branton kisses Dr. Weir and she becomes attracted to him, but she decides she can't allow anything to come of this; then the control tower reports that there was an explosion and three people are dead and many injured, and it is believed to have been a bomb.
