Until Dawn/Chapter 3

Ashley
The chapter begins with Chris, Josh, and Ashley in the midst of an attempt to communicate with some spirits. Naturally, the responsibility of actually speaking to the spirits falls on Ashley. You can take this seriously or choose to make a joke out of it; this only affects Ashley's personality traits and relationships in minor ways, so if you don't care to see how, disregard the next paragraph.

You can begin the seance by either being serious or flippant. While being flippant will upset Josh, Chris appreciates the joke enough that your relationship with him will improve. Use the next two choices to obtain some information about the mysterious encounter; it doesn't matter which, as you'll receive the same information in the end. For the following choice, you're given the option to probe or be apologetic. You can improve your relationships with both Chris and Josh by being apologetic. The next choice again has no consequences, as the same answer will be given regardless of the question. It is then that the seance ends, and the story transitions back to Mike.

Mike
Follow the path forward to begin the search for Jessica. Once you reach the truck, head left. At the end of this path is Danger Totem #2. Back at the truck, head right. After a scene, you'll have to decide how to react. Choosing to be witty, just as with the bird, is the best choice for Mike's relationship with Jessica. After another scene, look for Guidance Totem #3 to the left of the bridge before crossing it.

Back at the fireplace, turn on the lantern, then pack the fireplace itself with lumber and light a match to finally start a conversation with Jessica. Choose to reassure her at every opportunity in order to boost your relationship and get her to open up. After the scene, head through the hall to the back room and pick up the phone. Another scene will follow, and then it's back to the mansion.

Ashley
Before following Chris down the stairs, turn back around; to the right is a glasses case which you can pick up for Twins Clue #9. Now you can continue by heading down the stairs. To the left of a room is a floor vent that you can examine for Mystery Man Clue #10; just head left as soon as you enter instead of following Chris. After these two clues are collected, simply follow Chris until you can push a button for a scene, after which you are given control of him.

Chris
Head inside the secret passageway to find a photo that you can pick up for Twins Clue #8, and turn over for Mystery Man Clue #9. After speaking with Ashley, head into the previous room and through the door that seems to open on its own. Head left before opening the door at the end of the hall to find a note. Pick it up and turn it over for Mystery Man Clue #11. You can now open the door and continue into the mansion's main room for a scene.
