 * Tear Jerker: Wheatley reduced to a near-suicidal depression in the middle of the story. Seeing the normally upbeat and talkative robot-turned-cyborg in such a state is rather heartbreaking.
 * GLaDOS torturing Wheatley by . It doesn't take long for Wheatley to be reduced into nearly incoherent sobs.
 * and Chell's reaction to it.
