Chris
The chapter opens with a conversation between Josh and Chris. Josh's relationship with Chris will increase if you decide to show concern for him rather than gossip. After their conversation, Chris will encounter Ashley; choose to be confident to increase your relationship with her. Once that's done, before continuing around the side of the house to look for a way in, head back towards the camera. This will take you to another screen, where you have the option of speaking to Matt (choose to be friendly to increase your relationship with him) and Sam (no change in relationship). Right by Matt is the first totem of the chapter, Guidance Totem #2. You can now walk back to the mansion, taking a turn to the right to find an alternate exit.
Along the path, Josh will stop walking after bringing up Ashley, at which point you can press 
for a chance to greatly increase your relationship with him by choosing to agree with him both times. Once you reach the side of the lodge, examine the empty emergency axe case for Mystery Man Clue #4. To the right of it is a storage bin that you can push with Josh's help.
Once inside, use the lighter to find some collectibles. Loss Totem #1 can be found directly in front of you. Make a left and turn back to find another room. Enter to find a newspaper clipping on a shelf, and turn it around for Mystery Man Clue #2.
-
Go straight from where you enter to find this Loss Totem.
-
Mystery Man Clue #2 can be found in a small room to the left.
Return to the larger room, then exit through the door to the right. At a turn in the hall is a family portrait on the wall, which you can examine for Twins Clue #4. After another turn, open the door to enter a room that leads into the mansion's main hall, though don't ascend the stairs to the bathroom just yet. Across the room is Twins Clue #3, a prom photo on a short surface. From here, walk left into another room (past some locked doors) to find an answering machine. Interact with it to get it to play an interesting message, which also happens to be Mystery Man Clue #3. You can now head upstairs for one more collectible before going to the bathroom.
Once upstairs, turn left. Down at the end of the path, past a doorway and obscured from view is Twins Clue #1, a film trophy. You can now finally progress the story by making your way to the bathroom. Head through the wide doorway you passed by earlier and down the short hall, then through the sole open door. Open another door at the end of another short path to find the bathroom. Open the cabinet by the tub to find deodorant, which Chris will then take down to the front door.
-
A prom photo can be found on a surface to the left of the stairs.
-
In a room to the left of the first floor is an answering machine that can be activated for a clue.
-
The film trophy is hidden at the very end of a second floor walkway.

Turn the film trophy over for the clue.
Matt
It doesn't take long for things to get heated once the group gets indoors. If Matt saw Emily flirting with Mike in the previous chapter, he can now initiate a fight with Mike. Doing so will get Matt some affection from Emily and some distance from Mike. Make your choice to be directed into the next butterfly effect, which will be triggered automatically if Matt didn't see Mike and Emily together before.
Emily and Jessica get into a catfight, and it now falls on Matt to either back up his girlfriend or defuse the situation. The former will get Matt some points in his relationship with Emily, while the latter will upset her. While this decision isn't a very important one to make, it will affect how Emily treats Matt later on.
Mike
Follow Jess down the stairs. When she stops walking, talk to her for a short scene in which the pair take a picture. If you manage to get both characters in the frame, Jess will commend you on the good photo, though it doesn't affect their relationship either way. Continue to follow her down the path for another opportunity to talk to her, this time about Emily. As always, agree with her to improve your relationship with her. Once you reach the gate, take the path to the right to find Danger Totem #1 and the generator. Turn it on, then unlock the gate and continue to follow Jess along the path. She'll stop for a third time when she sees some police tape, at which point you can speak to her about Hannah and Beth. Choose to be respectful to improve your relationship with her.
After some more walking, the pair comes across the mines. Choose to be heroic and follow Jessica for some affection, as Mike will end up following her down either way. After moving the cart, follow the tracks, but be on your guard as a cart will roll toward Mike. Press 
to stop it. At a fork, take the winding right path to find Fortune Totem #1. Backtrack and take the left path. Up the stairs is a nook holding some clues to the right: a cigar stub on a barrel is Mystery Man Clue #5 and a drawing on the wall by the animal skull is Mystery Man Clue #6.
-
The cigar stub can be found on a barrel in a nook.
-
Right by the cigar stub is a wall with what looks to be a nonsensical drawing.
Turn back and take the path to the left. After a minor scare, you should see a table off to the right. Examine the map on top of it for 1952 Clue #1. Head straight until you're out, then take the left path at the fork to find Loss Totem #2. Follow Jess up the stairs and you'll eventually find yourself on a cliff, triggering a short scene. Open the gate to the left and head down some stairs. After being startled by a bird, choose to be witty to gain some more affection from Jessica.
-
On a table to the right is the first 1952 Clue, a mine danger map.
-
To the left of a fork outside is the final totem of the chapter.
A bit more trekking and you'll get a scene. The perspective will then switch to Sam back at the lodge as she attempts to get her bath going.
Sam
After exiting the bathroom, head into a doorway to the right. Sam should now find herself in Hannah's room, unchanged from the moment she disappeared. On a table to the right is a tattoo card; turn it over for Twins Clue #5. On the nightstand by her bed to the left is a postcard which you can also turn over for Mystery Man Clue #8. Finally, in the walk-in closet on the other end of the room, pick up a scrap of paper on the floor and turn it over for Twins Clue #6. Among some other items you can investigate for a peek into Hannah's life are the music box on her desk and a picture of Mike hiding beneath a party invitation on her corkboard, though you don't obtain any clues from them.
-
On Hannah's nightstand is a postcard with a familiar image on the back.
-
In Hannah's closet is a scrap of paper that you can turn over to find a compatibility test.
Once all clues are collected, you can finally proceed down the stairs to meet back up with everyone. After the scene, follow Josh down the stairs. He'll take a flashlight out of a drawer; above it is a picture that you can pick up and turn over for Twins Clue #2, which also happens to be the last clue of this chapter. But first, speak to Josh about Chris and Ashley. If you choose to be mocking, Josh's relationship with Sam will take a hit. After picking up the final clue, follow Josh through the door to the left. Josh will stop to talk to Sam again; either choice is fine this time.
After heading down the stairs, Josh will check out the water heater, at which point you can examine a baseball bat by the camera to his right. Choose to be serious after picking it up to improve your relationship with him. While it doesn't seem important right now, as long as you pick up the baseball bat, Sam will remember it later at a point where she may need it. After a particularly long "don't move" session in which Sam must hold the flashlight steady for Josh, she must now aid him in actually starting up the heat. Hold 
while moving 
around, then press again when the light comes on. High five Josh afterward with , a precursor to the following QTE. You can choose to protest or prank him back, it doesn't matter; the friends will start to hear some strange noises afterward. Choose to be heroic to impress Josh and earn some points with him, and after a short bit of walking, the QTE will begin.
Press 
to slow down the assailant with a mattress and 
to attempt to get the basement door open. On that note, you'll get another session with Dr. Hill, and the chapter will end.
