Neutral Route
Main article: Sans#Judgement

After walking halfway through the corridor, the protagonist encounters Sans as a silhouetted figure, paralleling their first encounter with him in Snowdin Forest. He initially speaks without his typeface and explains EXP and LOVE. Sans then asks the protagonist to look within themself and question if they have done the right thing. After a moment, he comments that it does not matter what the protagonist said, so long as they were honest with themself. Loading a SAVE and hearing Sans's introduction again prompts him to judge the protagonist on their earned EXP.

If the protagonist gained no EXP in a Neutral Route, Sans abridges his introductory dialogue and comments on their lack of LOVE. After this judgement, reloading a SAVE and talking to Sans prompts him to offer a secret codeword. After repeating this process a few times, the protagonist obtains the key to Sans's room.

If the protagonist killed Papyrus, Sans suspects that they may have some sort of "special power" and questions the protagonist if they should use that power to do the right thing. Regardless of their answer, he reminds them about his dead brother and ends the judgement there. Sans does not judge the protagonist on their EXP and LOVE, and this sequence repeats if the protagonist reloads their SAVE.

After his dialogue, Sans vanishes, and the protagonist can progress.

True Pacifist Route
Sans is not present in the Last Corridor during the True Pacifist Route, and the SAVE Point is missing.

Genocide Route
Main article: Sans/In Battle

In addition to the SAVE Point, a box is present, unlike in other routes. This is the location of the final encounter against Sans, in the Genocide Route. Sans attempts to prevent the protagonist from progressing because he believes they are the entity that ends the timeline.

After defeating Sans, the protagonist can progress to the Throne Room.

Geography
The Last Corridor is a yellow-hued room adorned with windows bearing the Delta Rune. White light shines through the mosaic windows, and Greek pillars border the corridor in both the foreground and background.

The goldenrod palette of this room may allude to the yellow SOUL which represents justice. The dual meaning of the word "justice" is a pun; Sans acts as a justice or a judge, and he also is just in character because he displays neutrality and objectivity. Sans also delivers justice to the protagonist if they are on the Genocide Route.
