Chapter 2 opens with you in someone's backyard.
Walk up the steps to the back door and go in.
Explore the first floor of the house and rummage through the kitchen area. Read the note on the refrigerator, drink the glass of water on the counter, get the walkie-talkie.
You need to leave the kitchen with the walkie-talkie and slip on the blood. Proceed into the living room and listen to all of the messages when a girl begins to talk to you on the walkie-talkie.
*While you do have dialog choices, you must run through every question with the little girl so they can be completed in no particular order.*
As soon as you find out that the girl is in the tree house you will be attacked by the baby sitter which will initiate a panic event. Battle the baby sitter which will span throughout the kitchen, and last long enough to receive some aid from Clementine in the form of a hammer. With the baby sitter beaten you have just completed Chapter 2.
