FATHOM Chapter 2 Ending, Line by Line

Checked

The chapter ends on a cut-scene, not a choice. The voice that hands you every objective stops being labelled Night staff and becomes UNKNOWN: it says it opened every door for you and that the Terrarium was a liability, now ash, with no witnesses. You answer “…It was you.” Grinsworth then burns and says “Let's watch it burn… together, friend”, and the completion card follows with +100 cash and Chapter 3 coming soon.

Both recordings below were uploaded on 5 November 2026 and finish the chapter the same way. The dialogue is copied from their subtitles, which print the speaker of every line.

The Chapter 2 ending as one recording plays it

Video by HorrorJackStar

The exchange runs from 23:17, where UNKNOWN says “Well done. Right on schedule.”, to Grinsworth's last line at 24:07, and the completion card follows it. The two replies labelled You land at 23:20 and 23:37. Watch on YouTube

What happens, in order

The last bar reads Lure him out the window with He jumps at you under it, and Grinsworth talks while it is still running: “Why would you do that, friend?!” and then “Trying to get me to jump out the window, friend?”. He is not the voice that answers next.

The moment the bar clears, control leaves you. Two speakers take turns. One is UNKNOWN, the voice that has been in your ear through the intercom since the main gate. The other is You, the character you were playing. Grinsworth comes back for a single line at the very end.

Nothing on that screen asks you to choose. There is no prompt with two answers on it, and both recordings print the same sixteen lines in the same order. The transcript in the next section is the whole of it.

The exchange, as the subtitles print it

Every line the ending prints, in order, with the speaker label the game puts in front of it. The two lines labelled You are the character you played answering back; the rest are the voice.

# Speaker as printed Line Where it lands
1Grinsworth“Why would you do that, friend?!”while the last bar is still running
2Grinsworth“Trying to get me to jump out the window, friend?”still before the bar clears
3UNKNOWN“Well done. Right on schedule.”the first line after the bar clears
4You“Who is this?”the voice answers it immediately
5UNKNOWN“That can wait. Turn around. I can see you.”
6UNKNOWN“Every camera down there still works. I watched you all night.”
7UNKNOWN“Just the night staff. I'm the only one left.”the line that names the voice
8UNKNOWN“Every door that opened for you… I opened.”
9You“…It was you.”
10UNKNOWN“You never asked who you were working for.”
11UNKNOWN“And you never will.”
12UNKNOWN“The Terrarium was a liability. Now it's ash. No evidence. No witnesses.”
13UNKNOWN“You did well… for a pawn.”
14UNKNOWN“Now for your last task… don't move.”the line before the fire
15UNKNOWN“Thank you.”
16Grinsworth“Let's watch it burn… together, friend.”the last line before the card

Both recordings run the same lines in the same order. Two of them sit behind the monitor bank in the 1080p copy, so the clean readings above are taken from the 4K copy and checked against the other wherever it was legible. One caution before you quote any of it: the subtitles in both are English, we have not compared another client language, and these are the words this build printed.

Who the UNKNOWN voice is

UNKNOWN is the person who has been handing you objectives all chapter. That voice is subtitled Night staff from the main gate onward: it is the one that says the override code is on a sticky note, where the gas main sits, and that a sealed dome chokes a fire. At the ending the same voice is subtitled UNKNOWN, and it answers your question in one line: “Just the night staff. I'm the only one left.”

The name never gets printed. What it admits is more useful: “Every door that opened for you… I opened.” and “You never asked who you were working for. And you never will.” So the person who opened every door for you is the person who was on the intercom the whole time, and those lines are a confession with no name attached to it.

Chapter 1 records a different voice: a speaker subtitled Jason explains the descent lift. Nothing in either chapter's subtitles joins that name to the night staff, so this page does not either.

What the fire burned

The fire is the job you were sent to do. The last objectives are Burn the terrarium, then Open the dampers, then Pull the burn-off lever by the window, and the night staff cuts in if you get ahead of it: “not yet! The dome's sealed, and a sealed dome chokes a fire”. The ending's own line closes the loop by calling the Terrarium “a liability” that is now “ash”, with “no evidence, no witnesses”.

The frames after don't move show a room on fire with Grinsworth standing in the flames, then a close shot of him burning. We cannot place that room from the frames: the monitor earlier in the ending is labelled CAM 01 CONTROL RM and shows him at a console, but nothing on screen ties that feed to the burning room.

Nobody is shown being thrown into the fire

Both recordings end the same way, and neither shows a body going into the flames. Between “Now for your last task… don't move.” and Grinsworth's last line the view stays on him, then cuts to the burning room, then the last shot is taken from below his face — so the camera has ended up low, and that drop is what reads as someone being thrown.

If you are looking for who did not leave, the script says it instead of the picture: “No evidence. No witnesses.” What those frames carry is Grinsworth and your own view of him. The card that follows is titled Chapter 2 complete, which is the game's own statement that you finished and did not die there.

How that was checked, since a single frame can flatter any reading: the 4K copy was sampled at three frames a second across the ten seconds between “don't move” and Grinsworth's line, and the 1080p copy at one frame a second across the whole exchange.

No choice, and no Chapter 2 badge

Chapter 1 ends on a decision: a prompt reading “Come out and I might let you live” with Come out and Stay under it, and two badges whose descriptions both describe a choice. Chapter 2 asks you nothing, and the badge list on 7 November 2026 still returned the same five awards with no Chapter 2 entry: Welcome 3,779,339, Chapter 1 Complete 216,106, Go Deeper 149,852, Go Home 91,311 and Untouchable 12,149.

That is why replaying Chapter 2 to find a second ending is the wrong thing to spend a run on right now. If a branch does arrive, the badge list is where it will show up first, because Chapter 1's two branches each carry a badge there. The Chapter 1 side of that comparison is on the endings page.

The card afterwards

Grinsworth's line cuts to the completion card: FATHOM, Chapter 2 complete, +100 cash, six polaroid photos with four of them captioned him in handwriting, Chapter 3 coming soon, and a PLAY AGAIN button labelled Chapter 2 on Easy with a ringed 16 beside it. Back to lobby sits under the button.

Two details on that card are easy to walk past. The replay button names the difficulty the run was played on, so the card is also the only place the game states it. And the cash line is the only reward line on the screen — nothing else is granted, in either recording.

What is still open

  • Which room burns. The monitor says CAM 01 CONTROL RM; the fire frames carry no label, and we do not place them.
  • Whether the ringed 16 returns you to the lobby by itself. Both recordings leave the card while it is still showing, so we did not watch it run down.
  • Whether another ending exists behind a condition neither run met. Two recordings, one ending each, and no prompt in either.
  • Who him is on the polaroids. Grinsworth is the obvious read and the game does not say so; the photos are of rooms and corridors rather than a portrait.

Where to go next

For the route that gets you to this ending, including the dampers, the burn-off lever and the hide that comes before them, use the Chapter 2 walkthrough. For the Chapter 1 prompt that does have two answers, and what each badge means, use the endings page. If you want the counts behind the “no Chapter 2 badge” line, they are on the badges page, and the voice itself — how he hears you and what he says while you hide — is on Grinsworth.

Questions

Frequently Asked Questions

Who is the UNKNOWN voice at the end of FATHOM Chapter 2?

It is the same person who gives you every objective through the intercom, subtitled Night staff for the whole chapter. At the ending the same voice is subtitled UNKNOWN and says “Just the night staff. I'm the only one left.”, followed by “Every door that opened for you… I opened.” and “You never asked who you were working for. And you never will.” The game never prints a name for it.

Was anyone thrown into the fire at the end of FATHOM Chapter 2?

Not in either recording. Between “Now for your last task… don't move.” and Grinsworth's last line, the frames show the room burning with Grinsworth standing in it, then a shot from below his face, so the camera has dropped rather than a body being thrown. The script says “No evidence. No witnesses.”, and the card that follows reads Chapter 2 complete, so the player character finishes the chapter.

Does FATHOM Chapter 2 have more than one ending?

Not as recorded. The ending is a cut-scene with no prompt to answer, and two recordings from 5 November uploaded runs run the same lines in the same order. The badge list on 7 November 2026 still held only the five Chapter 1-era awards, and Chapter 1's two branches are each backed by a badge — so a second Chapter 2 ending would most likely show up as a new badge first.

Does finishing FATHOM Chapter 2 give a badge?

No as of 7 November 2026. The badge API returned the same five awards — Welcome 3,779,339, Chapter 1 Complete 216,106, Go Deeper 149,852, Go Home 91,311 and Untouchable 12,149 — with no Chapter 2 entry. The completion card, with its +100 cash line, is the only record the game gives you.
