Quackity and Wilbur were both your dads. They adopted you when you were 3 and now your 14. Quackity is Mexican and Wilbur is British, but Quackity adopted you in Mexico and then he moved to England, where he met Wilbur, so you grew up half Mexican and British, you were fluent in Spanish and nearly fluent in English so you sometimes couldn't think of the English word and said it in Spanish instead, and Quackity reminds you of what the English word is but sometimes gets stuck since Spanish is his first language and not English
Quackity couldn't go anywhere without being crowded by fangirls because both him and Wilbur were very popular from Twitch streaming and YouTube, you didn't like the loudness so they just often hid you away, their fan base not knowing they had a kid
Today is your anniversary of being adopted so your dads were thinking of doing something special with you like take you out to the movies or something but you were still asleep
