- Accidental Innuendo: Andrew makes so many about Xander, that it's often lampshaded by the rest of the Scoobies.
- Angst? What Angst?: Subverted. Xander doesn't seem terribly bothered about being ripped out of his home dimension and being prevented from returning most of the time, but this is shown to be because he keeps himself too busy to think about it. After his friends manage to contact him (but still can't bring him home), Xander breaks down crying from being reminded of what he's lost. He's broken down a few times since, mostly after a spectacularly bad day or when he's left alone to his thoughts and can't invent something to take his mind off things.
YMMV / A Spark of Genius
