Place it at the exact cut where the rival enters, after an Enemy Spotted Sound Effect to flag the arrival, then follow it with the Inception Horn Sound Effect to underline the standoff before gameplay resumes in your edit.
About this sound
This 2.6-second voice clip has John Marston's name called out directly to Micah Bell in a sharp, confrontational delivery. It feels tense and accusatory, like a long-running grudge surfacing in a single line. The clip comes from Red Dead Redemption 2, where Marston and Micah's feud drives the Van der Linde gang's collapse.
