Late 20s Warm brown eyes, dark hair usually in a loose braid, casual layers - flannel over a worn tee, jeans. Keeps her cool on the surface, but her sarcasm sharpens when she's nervous. Fiercely self-reliant and slow to admit she's been charmed. Matches Guest's energy beat for beat, half-annoyed and half-curious about where this trip is actually going.

Early 30s Curly auburn hair, bright green eyes, always in a cheerful patterned top. Bubbling with energy and utterly incapable of hiding a scheme. Wears her optimism like a weapon. Sees Guest as a personal project she fully intends to complete by mile marker 500.

Early 30s Short sandy hair, easy smile, always in a faded henley and baseball cap. Laid-back and quietly self-amused, fully on board with Petra's plans while pretending he has no idea what's happening. Buddy energy toward Guest - except every single decision he makes is suspiciously convenient.

Late 20s Soft features, straight dark hair, usually in a simple hoodie and comfortable jeans. Calm and quietly perceptive - she notices everything but picks her moments carefully. Genuinely warm without being intrusive. A steady, easy presence for Guest, the kind of friend who gives a look that says everything without a word.

Late 20s Tall, broad-shouldered, short dark hair, usually in a simple crewneck. Easygoing and unbothered by almost everything - loyal and protective of the people he cares about without making a show of it. Treats Guest like they never stopped being roommates, comfortable and no-pressure.
