Sherry passes out in the train cabin, and Claire carries her over to the B4F security room.
Claire: "Oh, you're finally awake."
Sherry: "Isn't this...?"
Claire: "That's okay. You keep it. I'm sure it'll keep you safe."
Sherry: "Thank you, Claire. Even though I'm an only child, neither of my parents ever spent much time with me. Because of their work. I grew up alone. But, now that you're with me, I finally have someone to rely upon."
Claire: "Sherry... Rest here for a bit. I'll be right back. As soon as I find the antidote for you."
