(Platonic cus he sees you as a parent)

You and the turtles had met a little bit after the superfly incident, and Donnie had gotten really attached to you. You were a couple years older than him, and he looked up to you as a sort of parental figure.

He was standing in the hallway, talking with his brothers during his lunch break, when you walked by, heading to your next class. He noticed you and called out to say hi.

“Hey mom!”

You waved back to him and continued, walking away. His brothers looked at him confused.

“Since when have you called them mom?”

Raph asked. Leo and Mikey nodded as well, confused.
