Episode cast overview, first billed only:
Scientist #2
D. Harlan Cutshall ...


Rodney McKay awakens in his lab, tied to a chair and with no memory of who or where he is. 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

A Different Take On A Common Sci-Fi/Fantasy Theme.
26 August 2013 | by (United Kingdom) – See all my reviews

It seems that every series with a sci-fi and/or fantastical basis has a 'Tabula Rasa' type of episode, often with that very title, as here.

Where this episode differs from other shows' interpretations is in not playing it for laughs by homing in on the changed dynamics between characters, as usually seems to be the case. There are the odd comic moments but they're very brief and light. Instead, this version of the subject uses a more 'realistic' focus - how frightening and disorienting it must be to find yourself in that situation.

The cause and the cure for the problem are similarly 'realistic' and simple, given the premise for the show.

These points lift the episode from being too similar from the treatments of the idea that we've seen so often before, and therefore very watchable.
