Shaun was kidnapped as a baby for use in Institute experiments. He grew up there, adopted their ideas and beliefs, and eventually become their leader. He never knew anything outside the Institute aside from what he was told. The return of his biological parent prompts him to step outside the Institute for the first time and see the wasteland with his own eyes. Shaun deems his kidnapping a 'rescue' and expresses no hope for the recovery of the wasteland and those who live in it.
