Twins — Tag Meaning
Tags twin characters and the storytelling gravity they carry: identity swaps, uncanny synchrony, the private language, and the singular catastrophe of losing one's twin. Fandoms blessed with canon twins generate rich fic here; other fandoms invent them via AU.

Siblings
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.

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.

Identity Issues
Covers struggles with the question 'who am I?' — characters dealing with double lives, lost memories, inherited legacies, or selves that no longer fit. Fanfic gravitates to this tag for spies, shapeshifters, amnesiacs, and anyone whose canon identity is more costume than certainty.

Shenanigans
A cheerful catch-all for mischief, capers, and lighthearted chaos — heists that go sideways, group schemes, escalating pranks. The tag signals ensemble energy and a story where the fun is in watching characters cause and survive nonsense together.
