In the original Star Trek episode "Return of the Archons", there are two very different portrayals showing how the minds of outsiders are "absorbed" by the computer Landru:
In the scene prior to the opening credits, a brown-robed "lawgiver" approaches Sulu on the street, points his staff at Sulu, and fires. Seconds later, we see Sulu transported away. After he materializes in the transporter room, Sulu speaks strangely and questions why the rest of the crew is "not of the body". Sulu has been "absorbed".
At the end of act III and the start of act IV, the lawgivers visit the landing party in a holding cell. Instead of using the staffs they are carrying, the lawgivers escort McCoy, Kirk and Spock to the "absorption chamber", a separate room where the process of absorption is to take place.
I am trying to reconcile these two different scenes. What is the correct process to "absorb" a person? Why can it sometimes be done with just a staff and at other times must be done in a special room?
