A look at the various Easter eggs from 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!

CSI Tech Kelton - This marks the seventh and final appearance of CSI Tech Kelton. Kelton had appeared in past episodes, bugging Laurel's phone to record her conversations with the Hood, helping the SCPD track Felicity's hacks, and assisting in the SCPD's investigation of Cyrus Gold's break in of a Queen Consolidated building.

Kelton was played by Lee Vincent.

Gone but Never Forgotten

Clinton Hogue - Blood's bodyguard is named Clinton Hogue. In the comics, Hogue is the leader of a group of animal/human hybrids called the Splinterfolk. Hogue and the other Splinterfolk mutated themselves in order to access the Red, a primordial force that connects all animal life. It was later revealed that the Splinterfolk allied themselves with Brother Blood, who was trying to replace Animal Man as the Avatar of the Red. Hogue was created by Jeff Lemire, current writer of Green Arrow, and Steve Hugh.

Hogue, who's played by Roark Critchlow, also appeared in last week's episode but was not named.

Velox St. - When Felicity pulls up a map of Starling City on her computer, there are several street and place names, including Velox St. The Velox Valhallians are a Vancouver area rugby club. Since Arrow's production is based out of Vancouver, I'm guessing someone on the production team is a fan.

The Mirakuru Army - According to a picture posted by Marc Guggenheim, several members of Arrow's writing staff were soldiers for Blood's Mirakuru army.

Ravager - Isabel Rochev's new costume is similar to that of Ravager's, Slade Wilson's daughter. In the comics, Rose Wilson is the illegitimate daughter of Slade Wilson, and was hidden from Slade by her mother in order to protect her. Unfortunately, Slade's half-brother Wade learns of her existence and kidnaps her. During a rescue attempt by Bill Wintergreen and her mother, Rose's mother is killed and Slade discovers that he has another child. Rose also discovers that she has precognitive abilities, and briefly assists the Teen Titans.

After Slade's half-brother attacks her again, Deathstroke rescues her and offers to train her. Rose takes the name Ravager (which was first used by Slade's eldest son Grant, and then used by Slade's half-brother to mock him) and is injected with the same serum that gave Slade his enhanced abilities. Ravager becomes inflicted with psychosis as a result of the serum and gouges out her eye in order to be more like her father. Nightwing eventually rehabilitates Rose and helps her join the Teen Titans. She becomes an intermittent member of the team until DC rebooted its universe in 2011.

In the New 52, Rose is a member of NOWHERE, and briefly assists in training Superboy during his early days.

Cisco - Cisco Ramon, aka Vibe, calls Felicity at the end of the episode. You'll recall that Cisco made an appearance a couple of weeks ago in "The Man Under The Hood".

Kelton's Killer - The Mirakuru thug who killed Kelton played one of the alternate police androids in Fox's recently cancelled sci-fi series Almost Human.

And that's it for this week.
