Her two main Pokémon are Inferno, an Infernape and Echo, an Umbreon.
Rex was born to Lucian Victor and Emelia Dunst (whom was Lucian's girlfriend), after accidentally having sex with her while the two were drunk. She ran away while she was pregnant, but re-appeared in an insane asylum when that's when she decided to let them finally meet Lucian.
After several weeks, Lucian finally gained custody (in court) over them and now they both live with him.
Pokémon she has
She got her second Pokémon from Lucian for Christmas, whom captured an Eevee for her. Echo finally evolved when Rex ans she battled Roark for a badge. (And since Roark is a really sweet person, he let them both have a badge).
