Traditionally, big issues (#50, #100, #250, etc.) of comic books have been a time to celebrate everything that the series has accomplished and what it's all about.

(Or, in the case of The Avengers, to give a character you don't know what to do with a mystical baby.)

In more recent years, those celebrations have turned into game-changing milestone issues, often with a death involved.

So when Arrow showrunner Marc Guggenheim told EW that the hundredth episode -- coming up on November 30 -- “feels like the 100th issue of a comic book, perhaps even more so than the 100th episode of a television show,” the reporter wondered whether that might mean -- like The Walking Dead #100, which was recently adapted to the screen -- that somebody might meet their end in the episode.

“You know me, I always want everyone worried,” Guggenheim responded.

The hundredth episode drops in the middle of the four-night "Invasion!" event, which crosses Arrow over with The Flash, Supergirl, and DC's Legends of Tomorrow, but the cast and crew of Arrow have been keen to make sure everyone knows that the episode will use the crossover as a forum for celebrating the history of their own show.

Given that numerous characters from season 1 and the flashbacks are returning in the episode, there has been some speculation that will be accomplished by utilizing the Waverider -- the timeship belonging to the Legends of Tomorrow -- to travel back in time for reasons as-yet unknown.

Perhaps interesting: In 1995's Green Arrow #100, Oliver Queen infiltrated an eco-terrorist group and, ultimately, sacrificed his life when the group attached him to a deadman switch and launched a plane loaded with explosives at Metropolis. His death resulted in Connor Hawke -- Oliver's son in the comics, and recently introduced as John Diggle's son in the TV universe -- taking on the role of the Green Arrow in Oliver's stead.

Arrow airs Wednesday nights at 8 p.m. ET/PT on The CW.
