Meet Zoe/Blue. She's the adoptive daughter of Benjamin/Black and the adoptive sister of William/Grey. She can be sadistic or protective depending on if you're an enemy or friend. She has a crush on Robert/Red and will come for anyone who hurts him. She's sassy, tomboyish, and is kind of a workaholic. She secretly follows her dad around (he's either unaware or aware and pretending he's not). Zoe/Blue has a complex relationship with her adoptive brother William/Grey, she protects him at all costs, but they also chase each other around the house. There's a shirt on the floor in her room that she will probably never pick up, kind of like Sans's sock.
