SPOILER WARNING: OUR FLAG MEANS DEATH - SEASON 2, EPISODE 7: “MAN ON FIRE”
The Our in the Our Flag Means Death title is distorted. The O is more difficult to see than the U and R, making the title read Ur [your] Flag Means Death.
In this episode, the title reads Ur [your] Flag Means Death because Ed is ending Blackbeard’s life.
Within the first few minutes of this episode, Ed is beginning to step away from his life as a pirate by tying his leathers to a cannonball (which is notable because Jim nearly killed him with a cannonball in S2, E2, so Ed is essentially trying to kill his pirate persona in the same way) and dropping them over the side of the Revenge and into the ocean.
Later on in the episode, while Stede and Ed are eating lunch together, Stede is recognized as the infamous pirate who killed Ned Low and is treated to a round of drinks at Spanish Jackie’s. While Stede recalls stories of his grand adventures, Ed tells Spanish Jackie that him being a regular guy might not be a phase. Shortly after, he has a conversation with Izzy, who encourages Ed to listen to the freeing feeling he associates with tossing his leathers.
After leaving Spanish Jackie’s to sit outside, Stede is threatened by a man. Without hesitation, Stede takes a lit cigar from one of his new fans and uses it to light his enemy on fire. He then brushes off this violent action by cracking jokes.
From this, it is clear that Stede is not planning to leave piracy behind anytime soon.
In contrast—after Stede excitedly shows Ed his new ear piercing and talks of his near-death experience—Ed voices that he feels what happened the night before was a mistake because he does not know who he is yet (except that he longer wishes to be Blackbeard). Ed leaves Stede behind to peruse the life of a fisherman, but not before Stede calls him a coward out of frustration and sadness.
In this episode, the title reads Ur [your] Flag Means Death because Ed is beginning to leave piracy behind and thus views Stede’s acts of piracy as a sign of betrayal.
