Flack and Lovato have made their relationship known to the rest of the team.

They have a big effect on Mac who decides to propose to Christine. She accepts.
Scenes from episode 9x15 Seth And Apep can be seen during this episode.
Goof: When Jo is processing Theodore Hart's crime scene the victim and the scattered objects on the floor around him are in a different position than when he falls dead in the intro.
This episode follows three love stories gone wrong and each is given a subtitle: Love for Sale (Theodore Hart's case), Love is Blind (Bernard Chandler's case) and In the Name of Love (Jeremy Howser's case).
The action in the episode takes place on February 14th, St. Valentine's Day, one day before its actual airing date. We get a glimpse into some of the characters celebrating:
-Mac gets Christine a card and even though he can't make it to their planned dinner she arranges for them to meet at a nice bar with live music where they slow dance close together.
-Lindsay can't make it to dinner so she and Danny celebrate at home instead spending some quality time together, of which they've hardly have any for a long time.
-Jo is surprised by Ellie who has changed her plans with her boyfriend to spend the night watching sappy movies with her mum while they eat chocolate ice-cream.
-Flack fools Lovato into thinking that he had forgotten about the date and proposes beers and a slice as they watch a game together to make up for it. She is fine with that but Flack surprises her with a most carefully planned romantic dinner on a rooftop.
-Adam has VIP tickets for the Rockefeller Center ice-skating rink since Michelle has never ice-skated before.
The intro for this episode consists of music only without a single line of dialogue to accompany the images.
Goof: When Mac answers the phone when Christine calls the first time, you can clearly see the cellphone is showing a locked screen instead of an incoming call. The phone didn't really ring at all.
Rowena Black's apartment number is 914 and the police code heard over the radio when the vehicles are recovered is 9-Adam-14, both matching the episode number (season 9 episode 14).
The title of the episode White Gold refers to mozzarella cheese being smuggled across the Canadian border.
Adam has an older brother.
The episode title is a play-on-words with the curse of building 913, the date of the car accident when Jo's sister was killed and the episode airing order.
There's an urban legend around building 913 since Everett Harrington Wentworth jumped from the penthouse in 1929. They say the building was cursed on that very day. Wentworth lost all his money in the crash of the market and leapt to his death. His girlfriend, Wilma Ashton, watched his fatal leap and then killed herself. Many believe their ghosts roam the floors. The penthouse apartment is used as a haunted tourist attraction during the day, and a club at night.
Jo is from Alabama and went to undergrad in Tuscaloosa. She had a sister called Leanna who was killed by a drunk driver. Her heart was transplanted to Grant Holliston, a Physics professor also from Alabama.

Michelle, Adam's girlfriend, is a waitress and musician.
