[Both Shuukichi and Mary are startled at Kaiba's sudden appearance, but Mary, in her paranoia, is openly suspicious of him.

It's Shuukichi who responds first, trying to get control of the situation and make sure his sister will be okay.]

Will she be alright, if she goes back? I was worried something was wrong with her return, ever since I confirmed her body was still in the hospital, but she'll be safe on the train? [Shuukichi's deeply concerned about this, but is helpless to do much besides hope for the best.

Mary, meanwhile, continues to glare at Kaiba, but doesn't say anything. She doesn't trust the train to actually let its passengers go, and is worried that the passengers - Masumi included - are being tricked into trusting it more than they should. She also doesn't like that Kaiba is in the room at all or how he seemed to suddenly show up, and that's putting her on edge too.

(Masumi is busy just outside the room texting her friends to tell them she has to go back. They deserve to know what's going on too.)]
