Siblings — Tag Meaning
The broad canonical tag for sibling relationships as story focus — canon brothers and sisters, or characters written into sibling configurations. It promises the distinctive sibling register: a bond that predates personality, survives anything, and licenses honesty no friend would dare.
What to Expect From "Siblings" Fics
Sibling dynamics front and center, in whatever mix of devotion, rivalry, and shared-history shorthand the fic chooses.

Sibling Bonding
Tags siblings actively connecting: late-night talks, joint schemes, road trips, the patient rebuilding of a bond that distance or canon warfare eroded. It is the constructive sibling tag — where rivalry fics run on friction, bonding fics run on repair and closeness.

Sibling Rivalry
The competitive sibling register: contests over parental approval, professional one-upmanship, and grudges with toddler-era origins prosecuted into adulthood. Fanfic plays it for comedy, for tragedy in fandoms where sibling rivalry goes apocalyptic, and for everything between.

Protective Siblings
The canonical tag for siblings in guard-dog mode: shovel talks delivered to new partners, bullies confronted, and the immutable law that only I get to pick on my sibling. It celebrates protectiveness as the sibling bond's most visible proof, comedic or deadly serious by turns.

Brotherly Affection
Tags warmth between brothers (biological or chosen) expressed in the genre's native dialect: shoulder punches, gruff one-liners, and devotion demonstrated rather than declared. The canonical tag for fics that find the tenderness inside relationships allergic to naming it.
