So, I'm at episode 10... and while it is not the deconstruction that NXE was... There whole 'what is reality and what is really going on here' is really pushing the dial up to Big O's 11. Depending on where you place 10 on that dial, it might already be there; but with two more episodes after this one we are already deep in the pool.
Only other thing I can think of at the moment is that the translators made a major error. Those 4 are anything BUT JUNIOR high students. I'd argue that they were what us californians would call junior COLLEGE students, but I'm not sure the whole junior (aka 2 years to an associate instead of a baccalaureate degree) college thing is a thing anywhere other than California?
Of COURSE you wernt expecting it! No One expects the FANNISH INQUISITION! RCW# 86
