This is based off of the Family Dinner scene

Donatello had come to this Family Dinner with Splinter, and Leo, thinking it was to welcome someone to their apartment. Mikey and Ralph were already there along with April, and Barron Draksome.[sry if I spelt that wrong.] Donnie decided that if this was a Family dinner and April was there, he might aswell invite his Lover. So before he sat down he called you

Donnie: "Heyyy.."
