On-Screen Chemistry vs. What Actually Happens Between Takes
People always notice chemistry between actors on screen and then assume it translates to their real lives. It rarely does. Rhiannon Fish and Richard Harmon worked together on sets where that dynamic was visible, but the reality is usually far less dramatic than fan theories make it out to be. Fish and Harmon both appeared in the Supergirl universe around the same era. Fish played Mon-El in season one, and Harmon had a recurring role as Gabriel Walker. They shared scenes, and viewers picked up on the spark between them. The problem is that on-set chemistry is a manufactured product. Directors cast people together because they look good in frame, not because they're meant to be friends outside of work. I've been around enough productions to know that the distance between on-screen chemistry and off-screen reality is usually measured in coffee breaks and scheduled call times. When two actors play lovers or allies for months, they develop a working intimacy. They learn each other's rhythms, know when to hit their marks, and understand each other's performance style. That feels like connection because it functions like one, but it's actually just professional familiarity.
One thing nobody tells you about filming romantic scenes is how mechanical it gets. You're not being spontaneous. You're counting beats, watching a boom mic dip into frame, and hitting your three-quarter left while the camera operator calls out a zoom. I remember shooting a scene where the other actor and I were supposed to be sharing an emotionally charged moment. The director kept calling "cut" because someone's shadow was falling across the lens. By the fifth take, we were both just trying not to laugh. The audience sees romance. What actually happened was a logistics problem involving a reflector and bad timing. Fish and Harmon likely experienced something similar. The chemistry you see on screen is real in the sense that it registers authentically on camera. That doesn't mean there was a personal relationship behind it. It means two trained actors did their jobs well in front of a lens. Professional actors are skilled at creating the illusion of closeness because that's literally what they get paid to do. There's also the social media factor. Fans analyze every Instagram interaction, every comment reply, every subtle placement of emojis. This creates a feedback loop where speculation feeds more speculation until a theory becomes someone's accepted truth. I've watched this play out on multiple projects and it always follows the same pattern. A single friendly photo gets interpreted as evidence of a secret relationship. Then three more photos get dug up from years ago. Then someone writes a five-thousand-word thread connecting dots that don't exist.
The straightforward answer is usually the correct one. Two actors worked together, they were professional, the director shaped their interactions into something compelling, and then they went back to their separate lives. Neither Fish nor Harmon has made any public statements suggesting a romantic relationship existed. That absence of confirmation is itself data. If something meaningful was happening off-screen, at least one of them would likely have acknowledged it by now, especially in an era where actors frequently share behind-the-scenes content. What I find more interesting is how the industry benefits from this confusion. Romantic pairing narratives generate engagement, which keeps audiences watching, which keeps shows renewed. Studios know this. They don't encourage it openly, but they certainly don't discourage it either. A little ambiguity between cast members is free marketing. If you're trying to understand what actually happened between these two actors, the only honest conclusion is that there isn't one worth drawing. They worked together professionally. The chemistry was crafted on set. The offscreen reality is probably just two people who met during a job and moved on to different projects afterward. That's not romantic, but it's also not remarkable. Most on-set relationships end that way.

The harder truth is that fans sometimes resist this explanation because it's unsatisfying. A romantic storyline between real people is more entertaining than a straightforward professional collaboration. But entertainment value and factual accuracy are two different things, and they shouldn't be confused. The on-screen chemistry was genuine craftsmanship. The off-screen reality was likely pretty ordinary.
