Most of the places seems quite chill here. I would avoid 3 and 5 to not die, otherwise pretty much everything is pretty okay.

Ehh fairs fairs probably going to go one. Due to the fact that there's really no problem over there.

1, 6 and 7 for a chill time.
3, 5, 9 and maybe 10 if you like it dangerous.
2 and 4 for fun.
8 if you are into it.

10 actually the safest seat in the train, if you don't talk to her Corrin will leave you alone for the rest of the trip.

1 will burn off your eyes and nose, 2 will shut up Seth thus netting positive points with Jane, 3 is chemical disaster zone but you can lure Soukaku to it so it will turn into safe zone and will net you points for all 3 of them. Lure Miyabi to 5 in guise of 'advanced hostility sensing training' and then you will have the whole row of 6 free.
