The thread before was under the 'discussion' prefix tag, so spoilers lurked at the front page. No one discusses the latest chapter for some reason. I'm speculating they would be university literate and will be demotivated doing farm work by the time they got out. IIRC the spatial time is slower than on the outside (Ie 1 second outside; 20 seconds inside). jk, maybe we'll have more specialization this time around.
