Ruby gasped, her face turning deep red at the mention of parts, she surely wasn't referring to Crescent Rose's upgrades, but her own body's "upgrades," she tried to play off innocently, like she didn't know what she was talking about--she was, of course, trying far too hard. Ruby was almost happy that her mom asked another question, she was about to say that she was trying to pass as more human, her mom decided more teasing was in order.
"W-Winter?! I don't know who you're--" she bit her lip as she realized she didn't use initials that time, thus likely giving the demoness more ammo, but since she was bringing up the embarrassing details about the white hair, Ruby closed her eyes and resigned to her place in the dirt, hoping she didn't hear her say "W.S.'s" name.
She sat up silently and raised a finger that trembled more than a leaf in a hurricane, when her mother mentioned the hair, almost didn't hear her last sentence. She really couldn't answer like this, she was so embarrassed, she just wanted to crack the ground open, fall in, and hide for a while, "U-Uumm...I'm hungry, so how about I make us some salmon, I heard about this really good recipe recently!" Ruby, of course, wasn't about to say it was an Atlas specialty, but Isabel probably could've guessed who she learned it from--or through teasing cause Ruby's expression to betray her, with wide eyes practically screaming "How did you know, I never said Atlas!!!"
