Love is in the air for at least one character on The Flash. Season 3 saw Joe West through a budding romance with Cecile Horton, Central City's district attorney. Though there was a little trouble in paradise last year, it seems as though the couple will still be going strong when Season 4 picks up. At Comic-Con International in San Diego, Joe West actor Jesse L. Martin teased more development in his character's love life.
Asked about Joe's relationship with Cecile, Martin teased, "It's going to progress. That's really all I can say. She's going to be around, so we'll see what happens."
"I love the idea that Joe's got a girlfriend, so that gets explored," he added. "I really, really love that, because I spent so much time just dealing with the kids and the gang over at STAR Labs. Now I have somebody at home to deal with, in a good way."
Though Cecile debuted in the Season 1 episode "Who Is Harrison Wells?", she reemerged in Season 3's "The New Rogues" as a potential love interest for Joe. After a few missteps, the two began dating, only for Joe to break it off when the burden of keeping Barry's secret proved to be a strain on the relationship. However, at Barry's encouragement, Joe confided in Cecile and the two rekindled their romance.
Per Martin's comments here, it seems as though Joe and Cecile take their relationship to a new level in the six months between the Season 3 finale and the Season 4 premiere. Martin was careful not to offer any details, but his teases suggest something like an engagement could be on the way for the widower, though that is unconfirmed at this time.
Further, it's possible that Joe and Cecile's romance could have something to do with this year's four-show crossover between Supergirl, The Flash, Arrow and DC's Legends of Tomorrow. At the Television Critics Association press tour earlier this month, CW president Mark Pedowitz offered a tease of the event, saying only, “Romance is in the air.” Later, Flash executive producer Greg Berlanti expanded on that, explaining, “Our way of making the show bigger this year was to go even more personal, so it’s a big life event for a few different people on the show… There are many life events that happen.” A "big life event" could very much describe a wedding, which could mean nuptials for Joe and Cecile or some other pair, though that is purely speculative at this time.
Starring Grant Gustin as the Scarlet Speedster, The Flash returns Tuesday, October 10 at 8 p.m. ET/PT on The CW. The series also stars Jesse L. Martin, Tom Cavanagh, Carlos Valdes, Candice Patton, Danielle Panabaker, Keiynan Lonsdale and more.
