The Flash has famously paid homage to the 1990 series by casting John Wesley Shipp as Henry Allen, and featuring the likes of Mark Hamill, Amanda Pays and Alex Désert as guest stars. Tonight's episode, "The Elongated Knight Rises," adds another callback to that list with an appearance by Corinne Bohrer.

The actress, perhaps better known in more recent years for her work on Veronica Mars, reprises her role as Zoey Clark, aka Prank, the second sidekick of Hamill's Trickster.

In "The Elongated Knight Rises," she breaks her son Axel Walker (Devon Graye), aka the current Trickster, out of prison, imperiling Central City, Cisco and Caitlin. With Barry Allen imprisoned at Iron Heights, their only hope is ... Ralph Dibny, the Elongated Man.

This episode is a sequel of sorts to Season 1's "Tricksters," which introduced Axel as a copycat killer who sets off bombs throughout Central City, leading Barry Allen and Joe West to turn to Hamill's Jesse James, the original Trickster, who's been behind bars for 20 years. Axel breaks Jesse out of prison, taking Henry Allen as a hostage. However, in the end, their plan was foiled, and both were incarcerated.

Here's the synopsis for tonight's episode, "The Elongated Knight Rises":

When a familiar villain returns to terrorize Central City, Ralph (guest star Hartley Sawyer) must rise up to defend the innocent while Barry (Grant Gustin) is detained by his trial. Meanwhile, Barry searches for the strength to keep his optimism alive in the face of his new circumstances.

Airing Tuesdays at 8 p.m. ET/PT on The CW, The Flash stars Grant Gustin as Barry Allen, Carlos Valdes as Cisco Ramon, Danielle Panabaker as Caitlin Snow, Candice Patton as Iris West, Jesse L. Martin as Joe West, with Hartley Sawyer as the Elongated Man.
