Invisible

What had happened? Was her Prefects Badge so invisible? How could he neglect the blue and bronze of their own House? Why had Michael kissed her? He was in love with her sister…

Did Michael act upon an unconscious desire? Or was there more going on?

True, he was a lousy judge of character. He dated a lesbian and he found her sister annoying because she told the truth.

Was it just an act to hide his true feelings?

Well he was lucky he had caught her off guard. Otherwise she'd deducted point from her own House again, wouldn't she?
