If you don’t extract the Constant in Hitman 2 ’s Isle of Sgàil mission, the story still moves on: Lucas Grey takes over the extraction off-screen, and you can leave normally. In other words, skipping the extraction does not break the mission or change the overall outcome in a major way.

What changes

  • You miss the extra extraction dialogue and scene involving the Constant.
  • The mission still completes once you exit.
  • If you interact with the Constant in certain ways, some players note a timed consequence tied to the Washington twins, but simply leaving without personally extracting him still leads to the same broad result.

Important detail

The Constant is an optional objective in this mission, not a required kill target, so the game accounts for you not doing it yourself.

In plain terms

Think of it as choosing whether to do the handoff yourself or let Grey handle it behind the scenes. The mission ends the same either way, just with less unique dialogue if you skip it.

TL;DR: Nothing major happens if you don’t extract the Constant yourself; Grey handles it, and you can still finish the mission normally.
