Place this clip right after the accusation in your edit, then follow the denial with a bruh soundboard button for the reaction beat. That order lets the claim land first, the denial answer it, and the extra reaction close the sequence without needing another voice line.

This is a short voice clip of Markiplier clearly stating that he has never done drugs, delivered as a plain, matter-of-fact denial lasting just under six seconds. It feels funny and slightly exasperated, like a creator tired of being teased, which makes the deadpan line land as a defensive punchline rather than a serious explanation.
