And then (a head scratcher) in "Day of the Dove" the mysterious entity is seen floating in the balcony area where the red ladder is. But the entire time it is there, all the characters are looking over by the wall above the antimatter bypass room!
I just might fit another balcony on that side just to see how it would look...
Right now I'm trying to figure out where the Elaan and Scotty were when looking at what I assume is part of the deflector shield system and hoping it doesn't end up under the EMM
Got a screencap? I'm curious. (The Elaan and Scotty/ deflector shield reference)
Also, maybe since the entity could alter people's thoughts and perceptions, maybe it made them think it was where they were looking, while it made it's escape on the opposite direction!
Solves the issue of putting a second stepway where the "office" etc is located in other episodes.
