Everyone else probably knows this, but I didn't. You can see what would have happened if you'd made different choices.
Assuming you played to the end of episode 4:
- On the screen that says "episode 5 coming soon" there should be a left arrow on the left side of the screen
- Click it and choose wherever you want to rewind the game to
- When it asks for a save file, select an empty one
- play the game
If you don't see the arrow, then delete the sessionxxxx.estore, start the game, and do the above. It's in: Windows: %USERPROFILE%\Documents\Telltale Games\The Wolf Among Us OS X ~/Library/Application Support/Telltale Games/TheWolfAmongUs/
