A sus arc is the narrative stretch in someone's life or a group dynamic where one person goes from normal to deeply suspicious in everyone's eyes. Borrowed directly from TV and anime storytelling, the 'arc' framing implies that the sus behavior has a beginning, escalation, and eventual resolution — even if that resolution is just getting caught or finally getting cleared. Sus arc treats interpersonal drama with the same analytical seriousness fans apply to fictional character development, which is peak chronically online behavior.
