Nico worked to reinforce the shielding on the Cutter, just in case the ship wasn't as dead as their scanners said it was, while Max guided the team toward the core of the ship, avoiding the routes which were most likely to be blocked by defenders or saboteurs trying to keep others out of the core engineering areas.
The blockades that they did see were entirely too predictable to have been set by actual trained professionals. Whoever had sabotaged the ship had only gone for the most obvious of blockades, and anyone who knew the layout of the vessel would have known better than to leave all the crew access routes open.
That suggested that whoever it was, they were either very new, or had sneaked onto the ship at some point before the battle.
