Loop 2

Loop 2 is the second loop of Gnosia.

Summary
The same cast as Loop 1 is present, but this time the roles are randomized. Setsu explains that Gnosia has been detected onboard, and SQ insists she's not the Gnosia. The player has the option to call her a liar since they found out she was Gnosia in the previous loop. If they don't, Raqio will claim that saying as much makes her suspicious. Either way, the player gleans that though the players and stage are the same, something's different about the scenario.

Setsu and LeVi explain the procedures for dealing with Gnosia before the debate begins: everyone aboard the ship must decide amongst themselves who to the Gnosia is and put them into cold sleep. Aside from being standard procedure, this is also a compromise with LeVi: LeVi has no obligation to keep the crew alive at this point due to how dangerous the Gnosia are, so having some form of procedure in place is the only way they can justify not self-destructing.

During the debate, either the player or SQ will ask about what Gnosia is, the former unfamiliar and the latter having only vaguely heard of it. Setsu explains that the Gnosia are humans who have come into contact with the alien lifeform Gnos, with Raqio elaborating that little is known about it beyond speculation. The debate and vote continues as normal, though no matter how hard the player tries they will be unable to vote off Gina.

At night, LeVi shows the player around the ship, introducing it as the D.Q.O. They first visit the Rec Room, where LeVi asks what kind of game the player would like to play. Next they go to cafeteria, where LeVi asks about what food the player likes but sadly informs them that there's no time to eat. Finally, they head to the lower floor, where they find Gina in the EVA Room. They talk a bit, with Gina expressing her fear of what the Gnosia might do should the group fail and LeVi confirming the Gnosia are well worth fearing. Whether the player attempts to console Gina or not, she returns to her room after telling the player that she believes she knows who the Gnosia is and intends to explain tomorrow.

On Day 2, it's revealed that the Gnosia hasn't been put into cold sleep after all, with another character being eliminated. Gina speaks up and claims she's the Engineer, having credentials that allow her to analyze the dimensional waves of crewmates to detect whether or not they're Gnosia. She claims that the other surviving NPC is Gnosia, who may in turn claim that they're the real Engineer and Gina is the Gnosia. Gina asks LeVi to confirm her status as the Engineer, but LeVi informs her that they cannot do so, only aware that someone has Engineer credentials and not aware of who. It is left to the player to decide who they believe, as Gina and the remaining character will always vote for each other.

If the player votes for the other character, Gina will express her gratitude - not merely for being kept around, but because she's happy the player trusted her. She tells the player she hopes she'll see them tomorrow... and if it turns out she was the Gnosia all along, the player will realize she's lying and the game will tell them about Intuition and its ability to catch lies.

If the player votes for Gina, she will accept her defeat gracefully. The other character will allow her some last words, wherein she thanks they and the player and expresses happiness that nothing truly terrible had happened.

Trivia

 * If Raqio survives until Day 2, claims Engineer, and investigates Gina, this will be the first loop in which the player can see Definite Human be used; because Gina and Raqio will scan each other as Gnosia and there is only one Gnosia, the player must not be Gnosia.
