The Final Quarrel is a side mission in Borderlands 4 (BL4). This walkthrough will guide you through all objectives of the The Final Quarrel Side Quest.

  • Starting Location: Dominion > Terminus District
  • Quest Giver: starts by interacting with a Dumpster at the end of the alley north from The Food Court Safehouse
  • Unlock Requirement: Completed Side Missions The Neverending Quarry > A Quarry of Epic Proportions and interact with the dumpster to start the hidden side mission

  • Quest Description: It’s the jerk! Who apparently thinks he’s our nemesis? Fat chance, dude.

Objectives:

  1. Defeat ambush mastermind and jerk squad

Starting Location: The Final Quarrel

First you must have completed the side missions The Neverending Quarry & A Quarry of Epic Proportions. Then interact with the dumpster at the end of the alley north from The Food Court Safehouse. A flying enemy will pop out of the dumpster which immediately starts the quest. It’s a hidden quest, not marked by a “!” icon and not given by an NPC.

Defeat ambush mastermind and jerk squad

Defeat Frigid Horatio who popped out of the dumpster. He’s the mastermind who ambushed us in the previous two quests at the red chest and ammo vending machine. Also defeat the other enemies that spawn, the quest completes immediately after everyone is defeated.

This finishes The Final Quarrel side mission in Borderlands 4.
