In the Star Trek: TNG episode "Timescape", the Enterprise is trapped in a temporal anomaly that massively slows time. Picard, Data, and Troi beam over from a runabout in "normal" time, to examine what happened to the Enterprise. They decide to get around in the ship in the Jefferies Tubes, because the turbolifts are not in their time frame, and because they must conserve their own transporter power.
As they descend one particular Jefferies Tube, they find several Enterprise crew members blocking their way.
TROI: Should we go around them?
PICARD: No, we should take another route.
What are these crew members doing in the Jefferies Tube in this scence? In particular, are they doing something (or headed somewhere) specifically related to the plot of this episode, rather than routine work?
