Take the elevator up to the Deck.

Guest Cabin

Scan the handprint in this room. Step back into the elevator and take it to the Promenade again.

HANDPRINT (15/30)

Activate the elevator by solving the puzzle on the control box in the hall on the west side of the Promenade, then take the elevator up to the Deck. While in the Guest Cabin up above, scan the table on the left (south) side of the room. The table has some blood on it, and the handprint is right near that blood.

NOTE: Do not take the ammo or any items in the Guest Cabin. Leave them there, as Jill will need them much later.

Promenade

Use the Lifebuoy Key to unlock the iron door across from the Café. Move back up the stairs and backtrack through the hall past the walkway. Go back to the Grand Hall.

Grand Hall

Run up the stairs and use the Lifebuoy Key to raise the fence in front of the door to the Control Room Area. Open that door and the next door to trigger a cutscene that will end Episode 4: A Nightmare Revisited.
