-Fast forward up to when Tsugumi leaves the Control Room. Unlike last time, Takeshi follows her. He says he'll go with her too, but she says she has her own things this time, and won't be needing a keycard. Takeshi asks, "then what about ballast?" After a brief silence, Tsugumi just says, "Do what you like."
-As they travel, Takeshi notes that like always, she seems to know the way. Suddenly, Tsugumi stops, noting that while the pump room is up ahead, Sora can't scan there. Takeshi says he'll go ahead and check it out. Tsugumi says, "True, I might need a canary this time." Takeshi doesn't get it.
-Takeshi opens the doors, and is right outside the pump room door. Just as he's about to try the lever, Tsugumi asks, "How's it look?" Takeshi goes back to her and says it seems fine. Tsugumi asks if he has a headache, dizziness, or shortness of breath. When Takeshi says no, Tsugumi says it should be safe, and goes ahead.
-Tsugumi looks at the door, and asks Takeshi to remember the generator room. Realizing what she means, Takeshi stretches his hand out to the lever, and can feel the heat from it. Takeshi wonders how Tsugumi realized it, and they go off in the other route.
-They silently walk through the halls of the upper level. Takeshi wonders what Tsugumi's thinking about. He wonders exactly what Tsugumi is trying to find in "this nightmare she calls life." Tsugumi tells him to stop staring at her, and he apologizes.
-They arrive at the electrified hallway. They both agree it seems impossible to get through. Takeshi remembers Tsugumi saying she wanted to die, and he remembers his resolve to save Tsugumi from despair, and starts trying to think of a way to get through.
-He suggests shutting off the electricity, but Tsugumi reminds him of the blackout, and that they can't use the EI elevators this time. He then remembers You's lectures about temperatures the human body can take, how they can last about five minutes in a 100 Celsius environment, or the 400 Farenheit experiment in the USA.
-Takeshi then shouts that there's still hope, and we get a cut to the hallway outside the pump room, where Takeshi tells Tsugumi to wait (after having presumably explained his plan to her off-screen). She asks "Are you serious? Are you really that stupid?" Takeshi says it is stupid, but it's the only thing he can think of. He then tells her to believe that there's hope if it works.
-He goes to the pump room, and opens the door, despite the lever burning his hands. The hatch opens to another hallway, where it's boiling hot inside. He sweats and starts panting, but keeps going. However, it gets rather taxing.
-He hears Tsugumi asking if he's all right, and sees that she's coming along with him. Takeshi regains his willpower, and resumes walking. The heat starts getting to Tsugumi, prompting Takeshi to ask "Are you all right?" She answers, "I could ask the same of you." They support each other as they walk, and Takeshi can smell Tsugumi.
-Takeshi mentions Tsugumi smells nice, and she says "What the hell are you saying at a time like this!?" He says it's because it's a time like this, and they get back to their hope/despair discussion. He says "If this is a nightmare, you'll wake up someday, won't you?"
