Emma asks the guy if he's Minerva, and he says no. Ray asks to see WM, but the man said there's no one called Minerva in this shelter.
Ray asked where WM is, but the man tells Ray that he has no idea. Ray then asks who the stranger is, and what he is doing in the bunker. The man says that he's basically their senpai.
He ran away 13 years ago from Plantation 13: Glory Belle, thanks to the help of one of Minerva's pens.
He had not met Minerva when he arrived, so he thought it was all a lie.
But he had spent all this time living in the Shelter. It has all the necessary living conveniences (food, electricity etc.) also information about the world.
Emma asks about the others people that must have found their way to B06-32. The man tells the children that they are all dead and that he's alone there.
He had known that 15 children had escaped from the Grace Fields Plantation a week ago.
He says something about supplies in the shelter that were limited.
So he got rid of everything that was not necessary. Friends, hope and mercy.
Emma was about to raise an issue with this but he threatens her with a gun.
Not sure about this sentence, but seems he wants them to leave.
