"I don’t have time for this," you think to yourself. "I need to get moving."
You open the trap door and see a chute descending into the darkness.
With a rush of adrenelin, you jump in feet first.
With a rush of acceleration, you slide down the ramp.
With a rush of excitement, you feel the end of the ramp disappear behind you.
With a rush of gravity, you plummet 100 feet to a grisly death on the pointy stalagmites below.

Days later at your funeral, the members of The Order sit discussing what happened.
"I can’t believe Shrubbery took the chute meant to catch stupid lackeys trying to follow us if we had to escape. I mean, who labels a secret emergency escape route with a sign saying ‘Secret Emergency Escape Route’? Kind of defeats the purpose. Shrubbery should have waited for the contact."

I would suggest you return to the previous waypoint and make the other choice.
