Simpson

Doctor Simpson was a civilian scientist stationed with the initial Atlantis Expedition into the Pegasus Galaxy. She offered her knowledge and expertise to discover a means by which her team could dislodge a Puddle Jumper from an active Stargate.

Simpson countered Dr. Kavanagh's fears that the damaged Puddle Jumper would set off like a bomb upon returning to the Gate Room, saying the likelihood of such an event was extremely remote.

She has not been seen nor mentioned again since then.

It is assumed she either left for Earth after the seige or still remained on Atlantis.

She first appeared in Thirty-Eight Minutes.
