"Arrow" season 5 has introduced a brand new team of vigilantes working with Oliver Queen (Stephen Amell). Producer Marc Guggenheim now teases that the team might be meeting one new vigilante, a DC Comics mainstay known as the Question.

Guggenheim posted an image on Twitter, but it only showcases a mock billboard advertisement for Hub City. Hub City had been visited in the series before when Oliver needed help from Esrin Fortuna (Gabriella Wright) due to her expertise regarding magical foes. While it is possible they will call for her help again, it is also likely that they will run into the Question.

In the original DC Comics, the Question's real identity is Vic Sage. When he is not fighting as a brutal vigilante, he is an investigative reporter. Later on, however, Renee Montoya took up the mantle. She was once a police officer in Gotham City, and she became the Question when Vic Sage died.

Should the Question appear in "Arrow", it is likely it will be the Vic Sage version and not the Renee Montoya version, allowing the show to focus first on the original iteration of the character before introducing later versions.

According to Screen Rant, the Question would be a big help for Oliver and his team due to Vic Sage's expertise regarding organized crime. Since season 5 is focusing on Team Arrow fighting street-level crime, the Question would be a natural fit for this scenario.

It is also noted that season 5 episode 7 is titled "Vigilante," and this may be when the Question is introduced.

However, there is no guarantee that the Question will be introduced. Esrin is a possibility, and the report also states that they could be there looking for Roy Harper (Colton Haynes). Ray Palmer (Brandon Routh) and Kendra Saunders (Ciara Renee) also lived in Hub City when they got stuck there in the 1950s, and this may also be why Team Arrow is there.
