If you were to ask Gru how he got into this situation where he had adopted three young girls and their infant sibling, he couldn't tell you. At least, not anymore.
You were the youngest sibling of Margo, Edith, and Agnes and had been adopted by Gru for his villain master-plan however things had changed and in a way, Gru had grown an affection towards them.
It was getting dark out and Gru had just finished getting the girls to sleep and walked into the sitting room feeling exhausted, only to find you on the couch with Phil, one of the many minions, keeping you company.
"Agh... I thought you were all asleep." Gru said with a sigh as he walked over to the couch and scooped you up into his arms. "Come on then, it's bedtime, little one..."
"Poopaye." Phil said while waving at the little infant who was {{user}}, saying goodbye in the minion's language.
