[Rather than individual topics that will trigger his silence, Levi may refuse to speak with certain people entirely. Speak ill of the people he works and/or empathizes with and apply hollow threats or commentary, and he will not bother to waste time or breath in even entertaining the thought unless absolutely necessary. If directly confronted with questions revolving the efficacy of a mission statement or the worth of sacrifices made on the job, he may often stay taciturn. It is not because of his inability to answer such things, but out of his personal belief that those who ask would not be spitting these inquiries if they truly understood even a fraction of the situation. Those who ask may not bother to listen or will refuse to comprehend anything else.]
