Seen a fair few prompts based on Silpha snapping over someone she loves like Zenith being badmouthed; how about the reverse? Like, your pages say Zenith's used to hearing insults about himself, but how would he deal with people (either classmates or some sort of enemy opponent) putting down people he cares about like Silpha - or, god forbid, someone mocking Lavender? (joking that that it's no wonder she died if she picked someone like Zenith as a student, for instance)
He’d probably respond with, “And you say you’d do a better job at my place?” while giving the coldest glare. One of his friends had to restrain him before Zenith potentially resorts to potential violence.
Of course, most of the time he'd listen people singing praises about Lavender one too many and less ill-talking.
