Hm.. Never thought of them copy/pasting those traits. Since they all were personally acquainted with him, I assumed they would have drawn more on their individual recollections.

Ah... I actually meant to say "and one of his classmates from LLG"...
I was referring to Freron's comments (in which he also compares him to a cat).
The only descriptions I've ever seen of him from a teacher/employee of LLG were from Proyart, but those seemed a bit too bitter to be reliable...
