After Gilda (Leanne Lapp) wakes up to find Major (Robert Buckley) making a beeline from her bed to the door, you can hear him mumble/sigh, "Oh Rita." Gilda, the title role of the 1946 film, Gilda (1946), made Rita Hayworth a star, a sex symbol, and the ultimate femme fatale, but she seemed to believe it had a negative effect on her love life. She weathered several unsuccessful marriages and commented, "They fell in love with Gilda and woke up with me."
Matt Sudak (Daniel Bess) is referred to as "Su" several times. This is likely a reference to the Johnny Cash song "Boy named Sue." There is even a Johnny Cash poster in Lacy Cantrell's (Allyson Grant) room.
The lyrics to "Let You Go" as written in Liv's (Rose McIver) notebook read, "So you heard from some folks that I ain't been true. / I guess you still get gossip in the clink. / It happened one night, I's full of Soco and lime / When a Pretty Boy bought me a drink / And he said darlin', you're too pretty to be sad. / And I said Mister, I needed t'hear that real bad. / And come the next morning, I find Pretty Boy in our bed / And visions how you'd kill us in my head. / ----------- / There's only nightmares ahead of us / And sweet dreams long ago / It's time to wake up, baby / It's time I let you go / I've got to let you go" and, in parentheses, "Repeat x2", before she tears it out, crumples it, and throws it away.
