It’s time for the wedding, but Haley and Dylan weren’t expecting this many people, nor were they expecting music. Alex’s boyfriend plays the bagpipes and he has “science” that proves bagpipes are necessary for a good wedding. His mom’s first marriage didn’t have any bagpipes and they got divorced. Her second wedding did have bagpipes and they’ve still been married after 6 months. Unfortunately, this is a weak correlation at best, and most definitely not causal.
