SPOILER WARNING: This article contains major spoilers for "Into the Void," The Flash Season 6 premiere.
The Flash Season 6 premiere just offered some more insight into the mysterious case of Sue Dearbon. When "Into the Void" picked up, Ralph was away, traveling the world in search of Sue. He returned soon enough, then revealed Sue was missing and why this case stood out from the rest.
Indeed, he was missing from Team Flash's get-together when the episode picked up. As everyone gathered at Joe and Cecile's house for a cookout, Kamila mentioned she brought vegetarian hot dogs for Ralph.
"Guys, Ralph's still in Peru," Barry said.
"Or Monaco," Caitlin supplied. "Or Texas?"
"All that for a missing person's case? That's dedication," Iris mused.
When Ralph returned, he made his grand entrance in a tuxedo. This led him to explain a little about where he had been: "Picked this up in the Opal," he shared.
"A missing person's case sent you all the way to Opal City?" Barry asked, referring to the city that is Starman's hometown in the comics.
"And beyond, my friend," Ralph replied. "A summer spent undercover, rubbing Rolexes with the wealthy elite. Anyway, just following any leads that might help explain the disappearance of Sue Dearbon."
"I don't think I've ever seen you this devoted to a case," Caitlin pointed out.
"Me neither, but this one is a real tragedy," Ralph said. "Maybe it was the look of desperation in her parents' eyes when they begged me to find their daughter."
In the comics, of course, Sue Dearbon soon becomes Sue Dibny. Debuting in John Broome and Carmine Infantino's The Flash #119 in 1961, Sue was introduced as a New York socialite who married Ralph after a whirlwind romance. Occasionally working as an administrator for the Justice League, she moved around the country with him as he performed superheroics. She was murdered in 2004's Identity Crisis, sparking a murder mystery storyline, but returned in ghostly forms or otherwise during DC's New 52 relaunch.
At the time of writing, no casting has been announced for Sue Dearbon. However, she is on her way to the series. "We're going to pick up and Ralph is going to have investigated that file... on a journey that will eventually lead us to Sue," Ralph actor Hartley Sawyer teased at Comic-Con International in San Diego. The season will also reveal more details about his backstory and where he came from.
Airing Tuesdays at 8 p.m. on The CW, The Flash stars Grant Gustin, Candice Patton, Carlos Valdes, Danielle Panabaker, Tom Cavanagh, Jesse L. Martin, Danielle Nicolet and Hartley Sawyer.
