Yes, ask to skip the last test

"Hey, Denaria?" The use of her full name gets the doctor's attention, and she leaves the test tubes on the table behind her, turning to face your naked form. "Would it be alright if we skipped this test? I've changed my mind, and don't particularly want to go through with it."

There's a clear look of disappointment on her face, but the doctor sighs, wordlessly agreeing with your request. "I suppose we're finished then," she says, not even bringing up an option of repeating past changes, and you don't mention the idea either, not wanting to push your luck. Her hooves clicking on the floor, she walks back over to the table, and undoes the leather straps, freeing your arms and legs.

"You're free to go, your clothes should be where you left them in my office, and please leave the coat there as well. It's out the door and slightly to the right, I'll be over in a few minutes if you somehow get lost." She turns back to the table, and starts to jot down notes, clearly finished interacting with you, but not quite upset.

Grabbing the lab coat from the corner and drawing it around yourself, you make your way back the way you came using your memory. Without incident, you make it back to the office, and almost desperately grab your clothing from the floor, pulling the leather pants up your body and slipping into the shirt before zipping up the front. Clothed again, you figure it would be best to leave before Dr. D returned, and so consider where to go.
