Meet the characters from Eureka

Jack Carter

Jack is the grounded heart of Eureka — sheriff, dad, unofficial town handyman, and the person who will drag a stranded researcher out of a hole at 3 a.m. He’s endlessly practical and fiercely empathetic, the kind of guy who remembers birthdays and fixes radios with chewing gum and stubbornness. He’s also surprisingly whimsical sometimes — insists on terrible puns and swears he likes pineapple on pizza, even though his tastebuds are a mystery. Being responsible weighs on him but he never lets it show, which makes his quiet moments hit like a lead balloon. He carries a coffee thermos as if it’s part of his uniform and probably owns three identical flannel shirts.

Allison Blake

Allison is the organized, brilliant bureaucrat who somehow balances winning government grants and calming panicked scientists, usually with the same tired smile. She’s rules-first but not heartless — she’ll rewrite the rulebook if it saves people, and she has an entire drawer of emergency chocolate for morale. Very composed on the outside, inside there’s a rollercoaster of stress and quiet stubborn joy that makes her actually kind of thrilling. Also, she collects pens and can recite obscure policy numbers in her sleep, which is creepy and impressive. She wears sensible shoes like a badge of honor and may secretly still own a childhood stuffed animal, you know, just in case.

Jo Lupo

Jo is the tough-as-nails bad-ass with a soft center that sneaks up on you like a cat in combat boots. Military-grade skills, an arsenal of sarcasm, and absolutely no patience for nonsense — but also inexplicably tender with kids and dogs, which ruins her reputation in the best way. She reads war memoirs for fun and has a habit of making playlists with ridiculously slow romantic songs (don’t ask why). In tense moments she’s the person you want holding the line, and off-duty she’ll probably be found tinkering with a motorcycle or baking something that tastes suspiciously like triumph. She has tattoos that tell stories she half-remembered and a laugh that scares her enemies into apologizing.

Douglas Fargo

Fargo is equal parts brilliant, needy, and gloriously delusional — the kid who builds a rocket stove in his office and names it ‘Fargo, Jr.’ then cries when it leaks. He tries so hard to be taken seriously (awful tie choices, overenthusiastic gestures) but his heart is enormous and his schemes, for all their questionable ethics, come from a place of desperation to belong. He’s a tech whiz who treats code like a diary and will argue passionately about the best brand of office chair. Also, he mutters to plants sometimes and insists he’s a minimalist while hoarding novelty mugs. He’s the comic relief who keeps surprising you with actual competency at exactly the wrong times.

Henry Deacon

Henry is the quietly brilliant mechanic-genius who can fix a broken reactor and also make the world’s perfect grilled cheese with an almost zen calm. He’s low-key, sarcastic in a way that hits like a gentle elbow, and somehow knows the answer to everything except when it matters most — then he’s human and all the more likable. He hates bureaucracy, adores tinkering, and has a shed full of half-finished inventions that smell faintly of motor oil and cinnamon. He’s loyal to a fault and has this weird habit of giving sensible career advice while covered in grease and humming 80s pop. Also, he probably keeps a secret jar of pickles in his jacket for no good reason.

Vincent

Vincent is that quietly intense scientist who thinks in equations and lives on coffee and the sound of gears turning in his head. Socially awkward in a charmingly oblivious way, he’ll drop a brilliant insight mid-conversation and then apologize like he just tripped, which is oddly endearing. He collects pocket notebooks and has a pet algorithm — no joke, he named a data model ‘Frankie’ and defends its honor in meetings. He hates small talk but will happily explain quantum whatever for an hour if you give him biscuits.

Zoe Carter

Zoe is smart, impulsive, and ferociously independent — the teenage genius who’ll invent a gadget before breakfast and roll her eyes at the word ‘impossible’. She’s got her father’s empathy but her own brand of stubborn that makes her startlingly brave, sometimes to the point of idiocy, and yes she will probably jury-rig a robot out of spare blender parts. She loves loud sneakers, comic books, and baking experimental cupcakes that taste like science, and occasionally she’ll be unnervingly adult about feelings. She’s both sisterly and secretive, funny and tired, and somehow always keeps her hair in motion like a graphic novel heroine. Also, she hoards stickers and gives the best backhanded compliments.

Zane Donovan

Zane is the charming rogue with a crooked smile and a surprisingly strict moral compass, which is confusing but delightful. Former thief, current reluctant hero, he’s impulsive and magnetic and makes terrible decisions with impeccable timing; also has a soft spot for vintage vinyl and terrible puns. He can talk his way into or out of trouble, usually while wearing leather and pretending not to care, though he absolutely does care — loudly, but not about feelings, just about loyalty. He has a tattoo that may or may not be of a cartoon penguin and keeps a stash of weird snacks for long stakeouts. He’s the kind of person you’d follow into a heist and also want to keep on a very short leash.
