He did seemingly leave himself a video message telling him to look for Teyla. The problem began some 14 hours before when Dr. Katie Brown returned to Atlantis with plants from a planet she had visited. The plants had been cleared through the normal quarantine procedure but she is soon afflicted with severe headaches and loss of memory, eventually falling into a coma. Memory loss begins to afflict other members of the crew but they soon become distrustful of one another, making conclusions based on false assumptions and a misreading of the situation. Fortunately, there are two members of the team who seem to be immune. Written by garykmcd See less
