Johnson (Atlantis expedition)

Doctor Johnson was a scientist who joined the Atlantis expedition during its first year of existence. She died of a ruptured aneurysm in Atlantis on 2004.

(2004)
Johnson is part of a scientist team led by Doctor Rodney McKay checking for any damages in the previously flooded sections of Atlantis following the storm (SGA:, ). She and Doctor Wagner find an Ancient lab. Suddenly, as they are separated from the whole team, Wagner yells by radio they're need backup as "they" are attacking them. When the team arrive on place, Wagner is already dead. When McKay asks Johnson about what's going on, she panics, says she's seeing thing, agitating herself, and then collapses too, her nose and mouth bleeding. She's dead.

Later, Doctor Biro, under Doctor Carson Beckett's command, examines Johnson's body (after Wagner) and finds out she died of a ruptured saccular brain aneurysm just above the visual cortex as well as Wagner. Doctor McKay discovers this aneurysm has been provoqued by an Ancient nanovirus.
