No idea how or even if Jack Pot fits into Trixie’s story, but my headcanon right now is her parents are divorced and she is estranged from her father for some reason (jealousy of his success, or anger for leaving mother?) Perhaps her mother is passed and the two just grew distant. Hopefully we get a resolution to their situation in a future episode.
 
I thought about making a pic of an tearful confrontation between them, but then decided a tearful reconciliation would be a lot more satisfying.
 
Their colors really are nearly identical. Odd that she has an eye gradient but no highlights, while he has highlights but no gradient.
