Test Chamber 04
Wheatley at this point decides to mock Chell like GLaDOS did instead of motivating her, but isn't very successful at that, and it ends up in a discussion with GLaDOS until she calls him a moron again (making him very upset). The chamber once again features several bottomless pits and Excursion Funnel puzzles.
