After the communication device cutscene, your objective is to reach the bridge. Head back down the grand staircase. You'll notice a locked door on the first floor that requires a Ship Key. For now, ignore it. Instead, head to the opposite side of the first floor from where you entered the grand hall. You'll find a door leading to the Crew Quarters. Navigate through the narrow corridors, dealing with more Ooze. You'll eventually come across a room with a broken elevator. Nearby, you'll find the Ship Key on a desk. Pick it up.
With the Ship Key in hand, backtrack to the grand hall and unlock the previously inaccessible door. This leads to a new section of the ship. Continue through, solving a simple fuse box puzzle (match the colors) to restore power to a door. Once through, you'll find yourself on the bridge. Interact with the console to trigger another cutscene and complete the episode.
Be mindful of your health and ammo during this backtracking section. The Ooze can appear in unexpected places. Use your dodge mechanic to avoid their slow but powerful attacks. The fuse box puzzle is straightforward; simply rotate the fuses until the colors align. If you're struggling, examine the panel for clues on the correct sequence.
