Eeegh. Not one of my favorites, but I wanted a resident Addison, so...here she is. We'll get to my favorites soon, I promise.
Children
Addison paces around the locker room, wearing holes in the linoleum floor.
Derek catches her shoulders and makes her sit. "You'll be fine. It's just like teaching kindergarten."
"Derek, what if I screw up? What if one of my interns kills someone by accident? What if one of them stabs me with a pair of forceps?"
"Addi. They're kids here. They're just kids." She flicks invisible dust off her lab coat, and bites her lips.
"Just kids?"
"Yeah." If she ever catches herself flying with an umbrella, she'll commit suicide. Her interns stream into the locker room, and she might be ready for them.
Reference: Mary Poppins was known for flying with an umbrella. Books by P.L. Travers. Aaaaand that's it.
