Enter the house and get introduced to the others. When you have to pick some
music, walk to the stereo in the corner and make a choice that's cancelled out
anyway. When the beers are brought in, choose whatever you like, as your
conversation answers do not really have any impact whatsoever. After this, feel
free to do several optional things, such as dancing, grabbing/drinking a beer,
smoking pot in the kitchen, or (after doing or neglecting these) to continue
with the story, sit down on the couch/chairs.
Dancing: [All with RIGHT ANALOG STICK] Left, Up-right, Up-left, Up, Down.
Again, it doesn't really matter how you converse, but story-wise I would not
recommend letting Matt go too far on Jodie. When everyone insists that Jodie
shows off her powers, choose whatever you like. If you accept, interact with
the others and several objects in the room until you've made your point.
No matter what you've chosen, Jodie is put under the stairs. Unlock the door
with Aiden, then choose to either leave silently or take revenge. This is a
major decision story-wise, and leaves you with two different trophies depending
on what you choose:
Leave quietly: Bronze Trophy [Cold Blood]
Take revenge: Bronze Trophy [Revenge]
If you leave, the chapter ends right away. Taking revenge costs a little more
effort, but is also more satisfying story-wise. Head back into the living room
with Aiden and interact with the objects in the room to seriously scare and even
injure your peers.
