Since The Flash premiered on The CW in 2014, there have been significant changes in Central City over the past five years. Characters, good and bad, have debuted, left or died while those who have been a long-time presence have grown immeasurably in their own individual stories.
Although The Flash is generally lighter in tone than its sister-show Arrow, the body count has been quite high and has had an emotional toll on protagonist Barry Allen (portrayed by Grant Gustin).
In Tuesday’s episode ‘The Last Temptation of Barry Allen: Part 1‘, the titular hero endured mental torture in his own mind through an infection by current antagonist Ramsay Rosso/Bloodwork (Sendhil Ramamurthy).
Part of this ordeal, with Ramsay utilising Barry’s fragile mental state included showing headstones with the names of multiple deceased characters as a reminder of all the people Barry has lost since beginning his journey as the Scarlet Speedster.
Although they were mostly shrouded in darkness, quite a few were easy to make out – could this be hinting at possible returns? With the looming Crisis on Infinite Earths, anything is a possibility.
Detective eddie thawne
Detective Eddie Thawne (Rick Cosnett) was a main character during the first season. He was the police partner of Joe West (Jesse L Martin) and fiancee to Joe’s daughter Iris (Candice Patton), now married to Barry.
Eddie heroically sacrificed himself at the end of season one to protect his friends from Eobard Thawne and has yet to return properly, as Eddie after this event.
Rick Cosnett has already returned as Eddie from the past in Season 2 and the Speed Force in Eddie’s image during Season 3.
Barry’s father Henry (John Wesley Shipp) was a recurring presence during the first two seasons, before being murdered by villainous speedster Zoom (Teddy Sears).
We already know that Shipp will being appearing in Crisis as Earth-90 Barry Allen and presuamably Earth 3’s Jay Garrick. Why not add Henry to the mix?
Barry’s murdered mother Nora (Michelle Harrison), a key part of his journey to becoming The Flash, was also a clearly visible name on the headstones.
Harrison has already appeared in the sixth season as both Earth 3’s Joan Williams and the Speed Force in Nora’s image.
With this in mind and the tendency of someone resembling Nora being present during Barry’s darkest and emotional moments, I would say this is a definite possibility.
Barry’s ultimate frenemy, master criminal Leonard Snart (Prison Break star Wentworth Miller) could also be seen among the masses.
Miller has played multiple versions of Snart across the multiverse that the Arrowverse exists in but has not appeared in any of the shows since 2017.
Professor Martin Stein (Victor Garber) originated on The Flash before becoming one of the Legends of Tomorrow during that show’s early seasons. Much like Wentworth Miller, he actively stepped away from the superhero world and has not appeared in the fictional universe for some time.
However, executive producer Marc Guggenheim recently teased a return for Stein in the Crisis crossover as one of the three possibilities. The others were former protege Jefferson Jackson and Beebo from Legends of Tomorrow.
Barry Allen’s time travelling future daughter, Nora West-Allen (Jessica Parker Kennedy), was a prominent part of The Flash during its fourth and fifth seasons, spending the former as the elusive ‘Mystery Girl’.
Of all the character included, Nora was perhaps the most overtly referenced, as Barry also interacted with an infant version of his daughter.
The five-hour Crisis on Infinite Earths crossover event begins on Sunday, December 8 with Supergirl. As for whether any of those above make an appearance, we’ll have to wait and see.
