A look at all the comic book references and Easter eggs from last night's episode.

Welcome back to Arrow Annotations, the Internet's number one Arrow column. If you want to know more about the comics that inspired the TV show and random factoids about the latest episode of Arrow, you've come to the right place. Past articles can be found here.

If you enjoy this column, be sure to check out Flash Facts, my new column on Arrow's sister show, The Flash. And feel free to follow me on Twitter at @theouthousers. Now onto the comic references!

STAR Labs - Laurel gets tossed against a shipping container marked with STAR Labs' logo at the beginning of the episode. Of course, STAR Labs is prominently featured on The Flash, and it was first mentioned on Arrow last season.

Federal Marshal - The federal marshal dosed with Vertigo at the beginning of the episode is played by stunt actor Hugo Steele. Steele's been in a few episodes of Arrow, including the season 1 finale "Sacrifice", where he was a thug working for Malcolm Merlyn. You may recall that episode opening with Oliver being chained up and hung from a ceiling. Steele's the dude who tossed water on Oliver, waking him up.

Steele also appeared in Man of Steel as a Kryptonian soldier working for Zod.

Thea/Speedy - With Thea on the cusp of joining Team Arrow, it seems like it's a good time to remind readers that her nickname on the show, Speedy, has traditionally been the name of Green Arrow's sidekicks on the show. Thea's middle name, Dearden, is the last name of Green Arrow's most recent sidekick, Mia Dearden. Perhaps coincidentally, Thea was wearing a gold and black top, the same colors as Mia's costume, when Oliver showed her the Arrowcave.

Ned Foster - Oliver tells his mother via email to contact Ned Foster so he can write a press release telling the world he's alive. Foster is the Queen family's attorney and has appeared several times on the show, most recently at the beginning of the season.

Brodeur Chemical - During the first fight sequence with Vertigo and Laurel, one of the shipping containers is marked "Brodeur Chemical". Brodeur Chemical appeared in the first season in the episode "An Innocent Man." In that episode, Oliver discovered that Jason Brodeur, the owner of the company, had killed an employee and framed her husband for murder for whistleblowing on Brodeur Chemical's illegal activities.

Daggett Pharmaceuticals - Vertigo attacks Daggett Pharmaceuticals in the final part of the episode and takes several of its employees hostage. Daggett Pharmaceuticalsappeared in Batman: The Animated Series, and was the company responsible for creating the villain Clayface. The company's owner, Roland Daggett, appeared in several episodes in opposition to Batman. A John Daggett also appeared in The Dark Knight Rises, and was employed by Bane to force Wayne Industries into bankruptcy.

And that's it for this week. Thanks for reading!
