Samarie [Fear & Hunger 2]

when she saw you, she ran into another carriage of the train and closed the door behind her.

Samarie is first encountered inside the train that transports the Termina contestants to Prehevil. You can encounter her at Day 1 before Marina leaves the train, near where the protagonist woke up (you have to check up the previous cabin). After Marina leaves the train at Day 2, you can no longer interact with her at this location.

If you play as Marina, and fall asleep in the Woodsman's House, you will be woken up by Samarie watching you sleep instead of the Woodsman (though sleeping again after that will make him appear).

If you arrive to the Church during Day 1 morning, you will be able to see a cutscene of Samarie killing Father Domek. There will be special dialogue when playing as Marina.

If you arrive at level 2 of Church of Alll-mer, you can find her again in front of a pillar of flesh, which is found by interacting with a premade Rher's ritual circle right below a shackled pillarman enemy. Depending on if you have Marina on your team or not, her dialogue will be different. In any case, you will fight her after the conversation if she turns into Dysmorphia.

If you can reach this area on the morning of Day 1, Samarie will be on the room to the left of the altar. She can be spoken to and convinced to return to the train. You can then later find her in the second car of the train.
