Butterfly Effect Update: Sam escapes the Psycho
There are several factors to consider here:
Once the Psycho shows up, throw a base at him. Next, be careful of the single QTE along the stairs. Once you've reached the broiler room, choose to run. After encountering the closed door, choose Pull. After successfully getting through the door, lock it and close the hatch. Walk towards the wooden door and open it. Move ahead and you'll have the option to Run or Hide. Choose HIDE then press the appropriate QTE button. DO NOT MOVE. After this, the chapter will be complete.
Butterfly Effect Update: Sam gets caught by the psycho
If you selected any of the other options, made noise, kept running, and got attacked by the crow in Chapter 1 (if Chris shoots the squirrel in the shooting range), the Psycho will capture Sam during the chase scene in Chapter 5.
Butterfly Effect Update
[Chapter 7] If Sam escapes the Psycho, you'll be able to control her and explore a portion of the psycho's hideout, giving you access to the last Mystery Man clues to be found in the game. If she gets caught, she'll wake up tied in a chair but Mike lend a hand in freeing her up.
