That's actually a confirmed fact breh. Of course Namond wasn't gonna do shyt, but he had to pretend like he had Mike's back. Mike even thanked him when he came back.
Where's the confirmation?
Because to me it seems more likely that dikkriding Namond was just doing some more dikkriding than dikkriding Namond was subtly threatening one of the most feared killers in west baltimore. Maybe that's just my interpretation though
