Carl, Princess Donut, and Katia enter their newly merged level-five communal personal space, which begins as an empty hangar-like room. Donut places the party’s individual doors, the shared restroom, kitchen, living area, crafting studio, and a large training room, while Carl applies his enhanced crafting studio upgrade. A separate manager door also appears, giving Mordecai private quarters for the first time and confirming that the party’s unusually advanced base has unlocked benefits most crawlers do not reach early.

As they explore, Mordecai explains how personal spaces normally progress from small individual rooms to larger shared bases, and why combining three level-three spaces created something stronger than a typical communal hall. He warns that if Katia leaves or dies, the party could lose access to upgrades, and he advises Carl to keep his coupon in reserve until they know Katia will stay. Exhausted, Carl wants to sleep immediately, but Mordecai reminds him that his upgraded body now only requires two hours of sleep.

Donut insists Carl sleep in her room with her and Mongo. The ultra-stabilized bed works perfectly, and Carl wakes after only two hours feeling completely restored, earning a Well-Rested achievement and a powerful recurring buff to stats, experience, and skill training. In the common area, Katia and Mordecai serve a free meal from Wendita, and the group watches the recap show while Mordecai lays out a strict daily routine of buffs, one focused skill-training session, future crafting time, and then rail exploration.

During the show and afterward, the party gathers information about the Iron Tangle. Katia reports that the Daughters are also at a station numbered 83, suggesting that transfer-station numbers repeat across different colored lines. Donut wants to test the Nightmare line, while Mordecai shares that he previously appeared at station 317 with Yellow, Emerald, and Misery trains, so the group decides to start mapping all known routes through other crawlers. The top-10 leaderboard appears with bounties attached, showing Carl and Donut still ranked, Lucia Mar at level 30, and Mrs. McGibbons advanced to level 17.

The daily floor announcement changes the party’s plans by revealing that stairwells cannot be used early on this floor and will open only during the final six hours before collapse. It also confirms that top-10 crawlers can now be hunted for bounty rewards. When Carl opens his messages to contact Brandon, he discovers a special folder for deceased crawlers and reads Brandon’s final note, sent while he was dying on the third floor holding off Shade Gremlins so others could escape. Brandon asks Carl to tell his brother Chris that he was sorry and that he loved him. The message hits Carl hard, and instead of following Mordecai’s routine, Carl goes straight into the training room and attacks the dummies with Bare Knuckles, using grief and rage to keep himself from breaking.
