Mercy Lead

""Gimme three steps, gimme three steps mister, gimme three steps toward the door. Gimme three steps, gimme three steps mister, and you'll never see me no more.""

- Lynyrd Skynyrd

Sometimes, when the hero escapes right in front of the villain, they smirk and say "Oh, I think we can give him a five minute start." Alternatively, a criminal protagonist who's technically still due for arrest but has just assisted the law enforcement in something bigger will be given a Mercy Lead as an act of gratitude and good will.

Noble Demons and Worthy Opponents do this the most, to show that they respect the hero, and that they have style. After an Enemy Mine or Strange Bedfellows scenario, heroes usually give the villain a Mercy Lead, and the villain often reciprocates.

Less honorable villains may also promise a head start, but in such a case you can pretty much expect them to subvert the trope by breaking their word.

You might think there would be a case of heroes giving a villain a head start for no reason other than to maintain the status quo, but no hero would hold that big an Idiot Ball. Yeah, right.

Not to be confused with the bullet used to put some poor sod out of their misery.

Anime and Manga

 * In Spiral, the main showdown with Rio: the first to get both the tape of her confessing to murder and the hostage, Hiyono, wins.

Film

 * Pirates of the Caribbean: Curse of the Black Pearl—Jack Sparrow is given a day's lead by the Royal Navy.
 * The second film shows that the head start was a really bad idea: Norrington ends up in horrible situations (including a hurricane) because he was a day behind the Black Pearl, who outran said dangers by being a day ahead.

 * Gritty Noble Demon mercenary Vacendak has come to like the protagonist he's been chasing in the movie Freejack, and so gives him a five minute head start before he and his team begin their latest pursuit. He does so by literally closing his eyes and counting off the seconds, while the hero, once he realizes Vacendak's serious, sprints down the city streets to try to find somewhere to hide.
 * Played with in The Quick and the Dead, when Gene Hackman's character gives a mook who's displeased him thirty seconds to get out of town.

 * Played with in Baldur's Gate, where Bodhi gives you a non-specific amount of time to escape a dungeon at the asylum. Once you get far enough, she declares the time to be up and attacks you. Though it's in no way clear when she was supposed to come after you, the dialogue implies she's breaking the deal both of you understood you had.
 * There does exist a mod that will let Bodhi come after your party after a certain number of rounds have passed. Thus, it's possible that your party can escape the dungeon altogether without ever encountering her, or can wait at the beginning point and spawn camp her when she shows up.

 * In the Disney animated version of The Jungle Book, Shere Khan gives Mowgli a 10-second count because he's impressed at Mowgli's attempts to stand up to him and not run in fear.

Real Life
"When war-ships belonging to both belligerents are present simultaneously in a neutral port or roadstead, a period of not less than twenty-four hours must elapse between the departure of the ship belonging to one belligerent and the departure of the ship belonging to the other. The order of departure is determined by the order of arrival, unless the ship which arrived first is so circumstanced that an extension of its stay is permissible. A belligerent war-ship may not leave a neutral port or roadstead until twenty-four hours after the departure of a merchant ship flying the flag of its adversary."
 * In Dark Age Europe and The Middle Ages, the tradition of hospitality was so strongly honored that mortal enemies would stay their hands when sharing a common roof. It was the height of chivalry, or gentlemanly sportsmanship for the stronger to give the weaker a mercy lead before giving chase.
 * It is from this tradition, incidentally, that two belligerents will take it outside before a quarrel comes to blows.
 * The Union Cavalry did this for one Confederate partisan sentenced to be shot.
 * This is a tenet of international law, when both parties are in a neutral port. According to Section 13, Article 16 of the Hague Convention of 1907:


 * Ironically, the most famous application of this rule in history may just be when it was used during World War II to detain the German raider Admiral Graf Spee in the officially neutral Uruguayan port of Montevideo until British reinforcements could arrive — by secretly arranging for British and French merchant vessels to sail from that port every 24 hours whether their captains had originally planned to do so or not.
