Jadzia Dax runs a care facility for very young children on the station… who are Kira, Julian, Miles, Keiko, Sisko (pick one) Quark, Rom, Garak and possibly Morn.
Then one day, as she’s taking stock of the arts cupboard [Kira regularly breaks in] the bell rings. Someone new is coming to ‘class’.
It’s a bucket. Almost full of orange goo. Plastered on the side is a post-it that reads, “Free to a loving home”.
Just as she’s about to tip it out, the goo pours itself into the form of a small, doll-like child.
“I suppose you’re my 'mother’ now…”
