Fan Casting Walter in Library of Ruina

Walter maintains a stoic attitude in his work, acting in his supposed role as a "shield" of the Zwei Association. He seemingly espouses the values of the Zwei, but is also willing to resort to backhanded means like collaborating with the Stray Dogs to advance his mission. According to Salvador, Walter also has a habit of asking rhetorical questions, and tries to act clever while his actual thoughts are merely "one-dimensional." Salvador goes as far as implying that Walter is nearly talentless, only barely holding on to his position due to either his social skills or just pure luck.
