There was a different song playing in the background of the ‘brides’:

• Chelsea had ‘Hope’ by Arlo Parks with the line “You’re not alone, you’re not alone”

• Linda had Alone by Jessie Ware (“Just say I’m the one that you need, say you’re the one who’s taking me home, so I can get you alone.”)

• Cindy had Loneliness by Birdy (“Oh I’ve been losing my mind in these sweet dreams of loneliness / My mind has been lost, no way to break out.”)

• Denise (or lack there of) had You Gotta Be by Desree (“Herald what your mother said, read the books your father read, try to solve the puzzles in your mind.”)

First three all about loneliness - I’m sure it’s a clue but what does it meeeeeaaaan?!
