Alright lets be honest though,
1. Chad suspiciously gets interested in Sarah directly after her cheers are heard in the house
2. Chad puts up with her irrational behaviour for a week, no questions asked
3. Chad hears Sarahs booes and chants
4. Sarah continues her irrational behaviour and the relationship dynamic does not change at all
5. Chad gets visibly frustrated at Sarah all of a sudden, despite her not acting at all differently

The guy is attempting to play this game, not really a crime... but lets not pretend its genuine. He knows what he's doing.
