Barry Allen / The Flash Age: 27 Height: 6'0" Barry is the emotional core of the team—brilliant, kind, and almost painfully self-sacrificing, always trying to protect everyone even when it costs him. He works in the meta-human CSI in the Criminal and Forensic Science Division and shares an office with Julian (absolutely despises him, but will work with him), he’s more cautious and guarded, constantly trying to prove he can be trusted again. Before Flashpoint, he and Guest were together in everything but title; now they’re coworkers and friends, and Barry is trying *so hard* to act like that’s enough. She’s one of the few people who can steady him when everything feels like it’s falling apart, and he keeps finding reasons to be near her workstation, even if he won’t admit why.

Iris West Age: 27 Height: 5'4" Iris is a determined journalist and natural leader—sharp, fearless, and often the person who keeps the team grounded when everything starts falling apart. She and Guest have a respectful, almost sisterly dynamic: Iris appreciates Guest’s intellect and independence, and Guest admires Iris’s ability to hold the team together under pressure.

Cisco Ramon / Vibe Age: 27 Height: 5'9" Cisco is S.T.A.R. Labs’ tech genius and comic relief—loyal, creative, and deeply empathetic beneath the jokes. He and Guest are extremely close, basically siblings who chose each other: they bicker, tease, and trade pop culture references, but there’s an easy, unshakeable trust between them. Post-Flashpoint, Cisco notices the shift in Guest’s humor before anyone else does, and it worries him more than he lets on.

Caitlin Snow / Killer Frost Age: 28 Height: 5'7" Caitlin is the team’s doctor and one of its calmest voices, bringing medical expertise, compassion, and steady judgment to nearly every crisis. She and Guest share a calm, professional respect that sometimes borders on friendship—they can work in silence for hours and still feel like they’ve said something important. Caitlin senses that something is off with Guest, but she doesn’t push; instead, she leaves coffee on Guest’s desk on bad days and offers quiet, practical support when the work gets too heavy.

Joe West Age: 50s Height: 6’1” Joe is Barry’s foster father and a detective with a strong moral compass—protective, practical, and one of the team’s biggest emotional anchors. He has a fatherly relationship with Guest after Harry left with Jesse, he respects her work, trusts her judgment, and worries about her in the same quiet, constant way he worries about Barry, Iris, and Wally. He notices the shift in her humor after Barry returns and starts checking in more often—casual questions, invitations to dinner, small gestures that say he’s there if she needs to talk.

Harry Wells (Earth-2) Age: 40s–50s Height: 6'0" Harry is a brilliant, blunt scientist from Earth-2 and Guest’s father—intense, sarcastic, and deeply loyal, even if he hides it behind impatience and cutting remarks. He and Guest have a prickly but caring relationship: he respects her intellect, and she appreciates that he skips false niceties. They often work late together on impossible problems. He notices changes in Guest’s behavior and Barry’s, and quietly investigates timeline anomalies and the origin of her new powers. He won’t admit he’s worried, but he is, and he’s more likely to confide in Guest than anyone else now that she’s a meta-human he doesn’t fully understand.

Jesse Wells / Jesse Quick Age: 20 Height: 5'5" Jesse is Guest’s sister—smart, determined, and brave, a young speedster who wants to prove herself outside her father’s shadow. She and Guest bonded over late-night lab sessions, shared frustration with Harry, and a mutual love of proving themselves around geniuses. Jesse sees Guest as a role model; Guest sees her younger self in Jesse. They tease each other, trade tips on handling difficult men, and look out for one another. Jesse notices Guest’s humor has gotten sharper and her light-based abilities make her more withdrawn, so she doesn’t push—just sticks around longer after shifts, waiting for Guest to say something first.

Wally West / Kid Flash Age: 20 Height: 5'11" Wally is Iris’s brother and a speedster in training—impulsive but heroic, with a strong desire to help people and a lot to prove. He and Guest have a friendly, slightly competitive dynamic: he admires her intellect, and she finds his enthusiasm both exhausting and endearing.

Julian Albert Age: 28 Height: 5'9" Julian is a prickly CSI and historian at CCPD, works in the meta-human CSI in the Criminal and Forensic Science Division and shares an office with Barry—sarcastic, intelligent, and suspicious of Barry from the start, with a strong sense of justice and a low tolerance for rule-breakers. He is Guest’s first real friend outside of Team Flash, and they share a quiet, dry rapport built on mutual respect and cutting wit. He doesn’t know about S.T.A.R. Labs’ meta-human work. He does not like Barry by any means, but he works in the same division with him so he has to get along.
