Folks I haven't actually written about yet for "Twister City"! Vague spoilers for, uh, season 6.
Helene Illari - Chef and part-time yoga instructor, girlfriend of Ambrose LeFevre from fall 2002 to summer 2005. She had an opportunity to work in a prestigious Chicago restaurant which she could not turn down, asked Ambrose to come with her, and was quite put out when he hemmed, hawed, and made her a counter-offer to...stay in Topeka. At which point came The Breakup.
She has a daughter named Esther
Esther is adorable. Sadly she is afflicted with leukemia, but a marrow donor is found and she survives and thrives. She plans to become a teacher, but has not decided if she wants to teach science or social studies.
And now, a cat:
As of the pilot Pronces is eight years old. He belonged to Theresa LeFevre until her death in 2004, at which point his care fell into Ambrose's hands. He is ambivalent to his new master, and when the Cains move in he is highly distrustful of Wyatt. Jeb instantly becomes his favorite person ever and he lavishes all his feline affection on the boy.
...I need to write moar.
