A look at Easter eggs from this week's episode of Arrow.

Wondering what tidbits and easter eggs from the Green Arrow comic books you missed in last night's episode of Arrow? Arrow Annotations is here to help, providing some additional notes and background info from last night’s episode. Arrow spoilers follow!

Blackhawks – The Blackhawk Squadron is a DC paramilitary team that fought against the Nazis in World War II. Created by comics legend Will Eisner and Chuck Cuidera, the team consisted of a multinational group of fighter pilots, most of whom come from countries occupied by the Nazis. Although the war ended in 1945, the Blackhawks still had a monthly comic until 1968, and are still featured occasionally in comics. Lady Blackhawk, a time-displaced member of the squadron, was a prominent member of the Birds of Prey (and teammate to Black Canary and the Huntress), and DC briefly tried to revitalize the property as a “G.I. Joe” type of team in 2011.

This isn’t the first time that the Blackhawks have appeared outside of comic. The team had a 15 part film serial in the 1950s (starring Kirk Alyn, the first actor to play Superman) and made several appearances in the Justice League animated cartoon.

Ted Gaynor – This week’s villain, Ted Gaynor, is a former Blackhawk turned villain in the comics. Gaynor briefly appeared in the original Blackhawks series, serving as a replacement operative. However, his militaristic attitude and sense of entitlement eventually caused him to be forced off the squad.

Years later, he tried to sabotage Blackhawk Airways, a modern offshoot of the Blackhawk Squadron, only to be thwarted by Batman, Lady Blackhawk and Blackhawk, the founder of the Squadron.

Arrow Cave – As we’ve mentioned before, Ollie used to have an Arrowcave, which served as an early base of operations for the hero. It’s good to see Diggle call Ollie’s base by its proper name.

Carl Ballard – Moira is called in to stop Carl Ballard from gentrifying the Glades. Carl Ballard was the first criminal the DC superhero The Atom faced back in Showcase #34. In that story, Ballard manipulates an alien named Kulan Dar into using his shrinking powers to steal money.

Chaykin Gallery - Paul Knox mentions the Chaykin Gallery, a reference to Howard Chaykin, a prolific comic book writer who updated the Blackhawks in a three part miniseries in the 1980s.

Laurel and Sushi – Another reference to the Black Canary’s love of sushi.

Blake (henchmen) – One of Gaynor’s henchmen (the first one to get shot by Ollie) shares a surname with Lady Blackhawk, the first female member of the Blackhawks. Lady Blackhawk joins the Blackhawks in 1959. Due to the time warping effects of Zero Hour, she winds up in the present day and eventually joins the Birds of Prey as a member.

Vertigo (the drug) – Thea’s new drug kick shares the black and green color scheme of the villain Vount Vertigo, who’s set to make a debut next week.

Princess St. – Thea crashes her new car on Princess Street. How fitting.

Officer Gleason – The police officer who arrests Thea at the end of the episode is named Gleason. Patrick Gleason is a DC artist currently working on the Green Lantern: New Guardians series.
