Takes place when Robert lived with his parents before he met Amy. *Warning!*: very dark. Robert was having one of those nights. One of those nights where he stayed up wondering why he was so empty inside, if he was just being too dramatic, and if everyone would be better off without him.
Takes place all the way back in season 1 ep 5: "9 Lives." Just a bit of exploration into what Buzz's thoughts might have been after he's saved and everyone leaves.
