Reggie's girl

What if unsaid Emily wasn't about Luke's mum but his twin sister who just happens to be Reggie's girlfriend and Alex's best friend. Luke wrote unsaid Emily after the two got into a huge fight about her dating Reggie and him not spending any time with her. The fight was big and they both said things they shouldn't have and that lend them to stop taking for a year.
On the night of the Orpheum Emily snuck in to make peace with Luke, but when she saw him looking so happy she didn't want to ruin his big night, so she just snuck back out. When she got home, she heard that they died. It was like her world crushed down on her especially since Reggie left something behind.
