Stellar's mother
From Tardis Wiki, the free Doctor Who reference
Stellar's mother was shopping with her daughter on Iceworld. She got separated from Stellar when the little girl wandered off, resulting in Stellar and her mother being one of the few survivors in Iceworld.
Stellar's mother complained to Ace about lumps in her milkshake, resulting in Ace pouring the drink over her head and Ace getting fired. Anderson assured her that the milkshake didn't stain. (TV: Dragonfire)
