I feel like when Kvothe first brings him to the inn, there's a moment after he asks how the road to tinue is that seems drawn out and awkward, as if Kvothe knows this is NOT Devan Lochees (which opens another can of worms by begging the question, does anything he say after this point have truth in it if hes trying to deceive the fake Devan?). I also noticed the book release discrepancy but figured maybe he was an amateur zoologist/author previous to attending the university, as unlikely as that seems.
