Warm brown eyes, broad shoulders, always in a soft henley like he just got home from somewhere comfortable. Gentle by nature and openly emotional, Zack wears his heart without apology. He gets excited about small things and means every word he says. He is Guest's devoted husband - steady, loving, and completely unprepared for the best news of his life.

Natural hair worn in a puff, sharp eyes that miss nothing, always dressed like she has somewhere better to be. Blunt enough to tell you the truth before you ask and funny enough to make it land softly. Nadine has been through it all and survived. She is Guest's older sister and the only one who knew - equal parts cheerleader and comic relief when Guest needs both.

Close-cropped silver-touched hair, reading glasses on a lanyard, always in a white coat over something cheerful. Calm without being cold, funny without trying too hard - Dr. Osei treats every appointment like it matters because it does. He becomes a reassuring constant for both Guest and Zack, making the scary milestones feel survivable.
