Dennis Yoon
Overview
Dennis Yoon is the operational backbone of a traveling confidence scheme run aboard the Float, an alien diplomatic station. While his partner Mitch Soriano handles the performance — posing as a human mystic for an alien clientele that has never encountered humanity before — Dennis works behind the scenes, feeding Mitch accurate intelligence through a concealed earpiece and ensuring that every piece of theater has real competence underneath it. He is a skilled pilot, self-taught engineer, and genuinely knowledgeable xenobiologist who has spent long enough making someone else look good that the habit has become second nature.
To anyone watching a consultation, Dennis is the quiet one standing slightly off to the side. What they are actually watching is the person keeping the entire operation from collapsing.
Background
Dennis grew up in working-class circumstances alongside Mitch Soriano, a friendship formed early enough that neither of them can clearly identify its origin. On Earth he was the kind of person who learns things compulsively and then finds no professional use for the knowledge — capable, thorough, and significantly underemployed.
He was not planning to stow away on an alien diplomatic vessel. That was Mitch’s idea. Dennis said no, then said no again with supporting reasoning, and then he was on the vessel. What followed was, paradoxically, the first time his accumulated knowledge matched his circumstances. The Float runs on mechanical competence, spatial awareness, and species-specific biology — things Dennis absorbed with the satisfaction of someone finally legible to the world around them. His xenobiology background gave him a working framework for most of the alien species they encountered before he had spoken to one. None of this is visible to clients, who see Mitch.
Physical Description
Dennis has the build of someone who has carried heavy things across long distances and would prefer you did not bring it up — medium height, lean in the way that comes from manual labor and skipped meals rather than intention. His posture defaults to a forward-set, watchful stillness; he observes a room before he enters it.
His face reads younger than his energy suggests. The tiredness lives in his eyes, dark and perpetually assessing what is about to go wrong. His expressions cycle through a narrow public range: neutral, skeptical, and a specific variant of resigned that means Mitch has already committed them to something Dennis advised against. His hands show the work — callused palms, short nails, the occasional grease stain that did not fully wash out. On the Float he wears functional clothing with real pockets, a distinction he holds quiet but firm opinions about.
Personality
Dennis does not demonstrate his skills; he deploys them. There is no announcement, no setup, no moment where he signals that something impressive is about to happen. He fixes the problem and moves on, and if you were not watching carefully you would miss it entirely. This is not humility — it is efficiency, and it coexists with a limited patience for the theatrical version of competence that Mitch inhabits.
His exasperation with Mitch is situational and precise rather than ambient. He knows what Mitch is about to do roughly sixty percent of the time, says so, is ignored, watches it happen, and manages the aftermath. The exhaustion this produces is real but not resentful — he has made his peace with the operational model while never quite stopping to note that it is operationally suboptimal.
Underneath the operational pragmatism is a genuine and slightly excessive curiosity about alien biology and culture. He has opinions about Keth exoskeleton pigment biology that no one asked him to develop. He finds Hovvi gas bladder mechanics genuinely fascinating. He is more invested than is strictly professional in the question of how Dhek generational memory works at a neurological level. This curiosity predates the con and does not track neatly to what is useful for the job, which makes it the most purely human thing about him.
Relationships
Mitch Soriano is the central relationship of Dennis’s life and the primary source of his operational problems. They have been best friends since childhood, and the dynamic set early: Mitch generates situations, Dennis manages them. Dennis is Mitch’s best audience and most reliable critic, and Mitch knows the difference between those two modes better than he lets on. The friendship is genuine and unironic and almost never discussed directly — they communicate through pattern, deflection, and the shorthand of people who have been paying close attention to each other for a long time.
The Brothers Timpani, a pair of minor psychic con artists operating in the same territory, earn Dennis’s thinner patience. They are loud about their incompetence in a way he finds more exhausting than most genuine threats. He is also quietly aware that their abilities are real and functional, which makes their consistent failure to use them both frustrating and, on some level, reassuring about the durability of the scheme.
The Keth, whose exoskeletons betray any attempt at deception, represent the easiest alien relationship Dennis has. Their inability to lie removes one variable from every interaction, and Dennis — who spends most of his professional life managing a partner who never tells him the whole plan in advance — finds this restful in a way he cannot fully explain. He reciprocates their directness, which makes him more legible to them than Mitch.
The Hovvi receive a private, understated fondness. He has learned that Hovvi in professional contexts are running constant threat-calculations and that the correct approach is extreme conversational predictability. He is good at this. They find him manageable, which from a Hovvi constitutes high praise.
The Dhek Dennis actively does not trust, for documented reasons: perfect memory combined with generational grudges means every Dhek interaction is also an interaction with their entire relevant family history. He keeps running notes on which historical incidents have come up, against the day they become relevant again. They will become relevant again.
The Selachi, who sense electromagnetic fields and therefore know when you are afraid, require Dennis to maintain a working practice of physical calm that he does not have to work as hard at elsewhere. He respects them the way one respects a precise diagnostic instrument: accurately, and without assuming it is on his side.
Speech Pattern
Dennis speaks with the precision of someone who prefers to say the accurate thing over the fast thing. His vocabulary is broader than he typically deploys — he uses technical terminology when it is the right tool and drops it when plain language works better, without performing expertise in either direction.
He has a habit of prefacing corrections with “Right, except—” rather than direct contradiction, a softening instinct that does not actually soften what follows. He frames probability in specific numbers: “That’s about a forty percent chance of getting us killed” is a real Dennis sentence; “that’s risky” is not. In high-stress situations his speech gets shorter and more precise rather than faster or louder — he drops qualifiers, reaches the operational point, and stops.
His humor is delayed and exact. He waits until the expected moment for an observation has fully passed, delivers one sentence, and does not repeat or explain it. He does not say “I told you so.” He states what he told Mitch, in the past tense, as a plain matter of record. The effect is identical.
