CSI: NY

Same as it occurred in the season opener 8x01 Indelible the opening credits incorporate the old CSI:NY logo at the beginning of the sequence.

The very last lines of the episode belong to Macy Gray's song Coming Back To You and go as follows: 'I've been here before. I'll be coming back for more. Maybe this time I can stay' playing on the fact that the show's eventual renewal hadn't been decided yet when the episode was filmed.

The intro for this episode is way shorter than usual and doesn't have any dialogue.

Sid has used some of the money he has made out of his Hammerback Sleeper pillow to make a donation to The Hammerback Research and Forensic Development Center at Chelsea University.

Mac knew that Flack had shot Simon Cade dead after he killed Jess in 5x25 Pay Up and decided not to act on it.

Goof: Mac mentions that the Giants won the Super Bowl the year that Jess died. However, the episode where Jess dies (5x25 Pay Up) is set up on May 20th, 2009 and that year the Super Bowl winners were the Pittsburgh Steelers vs the Arizona Cardinals.

Mac's full name is Mac Llewellyn Taylor. His middle name is Welsh, coming from his mother's side.

The action in this episode has a time span of 6 months.

The prayer that Christine is saying at Mac's bedside is called The Apostle's Creed. The version she is reciting is from the mass of the Roman Catholic Church.

Lucy Messer is turning 3 years old.

As it was the case of episode 6x17 Pot of Gold, there are several references to Ireland, its people and folklore:

Episode title: Slainte.
Slainte is Irish for 'health', used as a driking toast.

Declan Callahan: Luck of the Irish, huh?
'The luck of the Irish' is a catch phrase that is used to explain the good luck that makes a person of Irish descent beat some odds. Since Irish people have historically suffered many misfortunes, there seems to be some inexplicable and inherited form of good luck that makes things come out right for them.

Flack: You are stuck here with us while Declan lives the life of Riley down at his bar.
'The Life of Riley', a phrase meaning 'to live an easy and pleasant life' originated in the Irish/American community in the USA.

Mac: 8th to 12th. 34th to 59th. 59th and 12th. It's the corners (of Hell's Kitchen).

Mac: It's not even called Hell's Kitchen anymore.
Jo: Clinton does have a nicer ring to it.
'Hell's Kitchen', now referred to as 'Clinton', was a century-old hangout for Irish immigrants. The four semi-traditional boundaries or corners of Hell's Kitchen are the Hudson River west, Times Square east, Chelsea/Penn Station south, and the Garment District north.

The case in this episode is #07-400-1027.

Ever since Sid became a millionaire (in ep 8x13 The Ripple Effect we learnt that he sold the patent of his Hammerback Sleeper for $27 million to a Japanese company), he has indulged himself on a Dyson vacuum cleaner. He made a list of all the things he wanted to buy and it only came to $56,374.63.

Onycholysis is an injury where the fingernails detach from the nail beds. Even though it can be caused from fungal infection or psoriasis lately it's affecting people who do repetitive manual tasks for long hours, above all young people, hence it's come to be known as 'Blackberry thumb' or 'Nintendinitis'.

Like many other characters in the show (Flack, Mac, Lindsay, Jo and Hawkes) Adam borrows Danny's distinctive line 'boom' in this episode.

Despite claiming to have been good at videogames some years ago (having a perfect Sunday deliveryin 'Paperboy') Lindsay beats Danny at 'Halo' and Adam beats him at 'Gears Of War 3'.

Flack used to be very good at 'Street Fighter 2'.

Mac used to bring a bag full of quarters to the arcade and set up in front of the 'Asteroids' machine for a whole Saturday.
Gary Sinise used to spend his evenings and weekends playing 'Asteroids' at the mall by himself when he was performing True West in NYC.

The case they work on during this episode is case #2012/52001.

Adam, Mac and Jo are good players at 'Gears of War 3'.
