Spoilers ahead for Episode 11 of The Flash Season 4, called "The Elongated Knight Rises."
The Flash has been making nods to past superhero projects from its very beginnings at The CW. In fact, the show went so far as to bring the actor who played the '90s TV Scarlet Speedster back to play Henry Allen. Mark Hamill signed on for a role as well, and it just so happened to be the same character he played then: the Trickster. Now, in "The Elongated Knight Rises," The Flash made its latest awesome connection to the '90s series, with Corinne Bohrer reprising her role of the villainous Prank, which allowed the show to give viewers a blast from the past.
"The Elongated Knight Rises" revealed Axel Walker -- a.k.a. Prankster 2.0 -- is the son of none other than the original Trickster (Mark Hamill) and a woman going by the name of Prank (Corinne Bohrer). When Joe was explaining the situation to Team Flash, they saw a photo of the lovebirds from back before they conceived their son. That photo just so happened to be a shot from the episode of the 1990s Flash that featured Mark Hamill and Corinne Bohrer as the Trickster and Prank. The Flash managed to cast the same actors in the same two roles on two different shows nearly 30 years apart.
Of course, the fact that John Wesley Shipp played Barry Allen, and not Henry Allen, in the 1990s series means that the two Flash shows don't exist in the same continuity, so these versions of Trickster and Prank aren't the exact same versions played the first time around by Mark Hamill and Corinne Bohrer. Still, it's fun to imagine that the '90s Flash show and the current Flash show on The CW simply take place on different Earths in one multiverse. Who's to say that these two people weren't destined to become Trickster and Prank in every timeline of every Earth, even if a different Allen became the Flash?
Unfortunately, Mark Hamill didn't once again appear in the flesh in "The Elongated Knight Rises," but you can take a look at him in action with Corinne Bohrer in this clip from the 1990 Flash show:
We'll have to wait and see if we get more Trickster tricks from The Flash in the future. The whole family is still alive and as mischievous as ever at the end of "The Elongated Knight Rises," and anything is possible on this show. Tune in to The CW on Tuesdays at 8 p.m. ET for new episodes of The Flash, and don't forget to take a look at our midseason TV premiere guide.
