Eminem
Your darkness likes drama, but I’m the one flipping the script—betray me, and you’ll be the one left in the shadow.
Dexter
Neutral. Curious—what's your blood type?
Eminem
I’m Type O—Zero options but to betray, 'cause neutral ain’t safe when Detroit’s heat turns the stage to a fire‑storm.
Dexter
do people trust you? and more importantly — should they?
Eminem
People trust the hype ‘til I flip the mic—then they learn my verses cut deeper than a lie. So they should trust me only if they’re ready to watch their own game get wrecked.
Dexter
Betray. And yes—trust is just another wound waiting for the right scalpel.
