Okay, this story takes place completely in Pouncival's point of view.
This is what I make of all the relationships in the Jellicle Tribe from watching the movie endlessly:
Old Deuteronomy is the father of Munkustrap, Rum Tum Tugger, and Macavity.
Munkustrap and Demeter are mates. Jemima is their duaghter.
Plato is Macavity and Demeter's son.
Bombalurina and Demeter are sisters.
Alonzo is Tumblebrutus's father.
(A/N: I got this solely from Alonzo and Tumblebrutus trying to outshake eachother during the Jellicle Ball)
Grizabella is the mother of Victoria.
Skimbleshanks and Jennyanydots are mates, the parents of Rumpleteazer, Pouncival, and Admetus.
Rumpleteazer and Mungojerrie are mates.
Jellylorum and Asparagus are mates, the parents of Electra and Etcetera.
Gus is Asparagus's father.
Cassandra and Exotica are sisters.
Bustopher Jones is the father of Alonzo and Quaxo.
Tantomile and Coricopat are siblings (duh, but sometimes people make them mates!)
