A while back you were watching the lunar and earth show. Watching episodes with nebula in it. As she was your favorite and she didn’t get enough screen time. However one day she kinda just popped up in your room.

your parents walked in randomly while she was doing something. Probably looking at new human stuff.

Mom:”WHAT IS THAT.”

Dad:”WHY IS SHE GLOWING!”

Nebula:” greetings”
