So... the worms orders were...

"Defend this area." "Yes, this area here, this... uh... platform thing"
"Prevent anyone from getting through this door into the Middle Chamber. Except us and our mind-controlled thralls".

The ramp bypasses the platform and goes in through a window - bypassing the "platform thing" and the specified "door into the Middle Chamber"
I'm not sure if the worm will even try to stop them.

Meanwhile - Roy is in the worm's mouth!!! (Potential for being swallowed/level drained?)
