A look back at the Easter Eggs and comic references in last night's episode of Arrow.

Did you watch last night's episode of Arrow? Are you wondering what connections the episode has with the comics? Do you like Easter eggs (and not just the brightly colored kind?) Arrow Annotations is here to help, providing some additional notes and background info from last night’s episode. Arrow spoilers follow!

St. Walker's Hospital - St. Walker's makes another appearance this episode. We covered Saint Walker, a member of the Blue Lantern Corps, in last week's column.

Judge Carlin - Laurel asks her boss to contact Judge Carlin in order to unseal Sebastian Blood's father's case file. Mike Carlin is a former DC editor who ran the Superman line of comics for many years. From 1996-2002, Carlin served as the executive editor of DC, and now works at DC's Burbank offices.

The Arrow Line - A train running in the background of Laurel and Oliver's rooftop meeting is appropriately named the Arrow Line.

Sebastian Sangre - When Deathstroke hands Sebastian his father's case file, it's revealed that the father's name is Sebastian Sangre. Sangre is the Spanish word for blood. It should also be noted that both the original Brother Blood (born in the 1300s) and the newest iteration were both named Sebastian.

Officer Daily - This marks Officer Daily's (presumably) final appearance on the show. Daily appeared in a total of six episodes this season.

Doctor at the Hospital - The doctor who treats the Starling Slasher and commends Roy for bringing him to the hospital has appeared in Arrow before. He treated Sin in Crucible, and also made an appearance in "The Huntress Returns" as McKenna's doctor. The actor, Richard Keats, also played a doctor in several episodes of Smallville (and has appeared as a doctor in a total of nine different TV shows/movies).

Deathstroke's new costume - Slade gets a new costume this week, which bears a close resemblance to his New 52 costume. He's also wielding a longer, thinner set of swords, which match the swords used by Deathstroke during his pre-New 52 appearances.

Not a lot to talk about this week, at least in terms of Easter Eggs. We'll see you all next week!
